A Year in Review: 2012

Since I wrote about my 2013 New Year Resolutions I decided to review 2012 and all of the genealogical achievements, discoveries and even unanswered questions that came with that year. That way I'll have a summed up version of all the posts of that year and can aspire to learn even more about myself, my family and their journey from all parts of the world to make me who I am today.

2012

April
  • Talked about the cousin I was able to meet through my blog. 
  • The release of the 1940 Census!!
  • Discussed the Y-DNA results I got from GeneTree.
  • Got to see for the first time the 1940 Census after its release and found some ancestors.
  • Posted about being able to visit the grave of my great grandparents (Alejandro Rivera González and Mercedes Ortiz Marrero) as well as some great-aunts. 
  • Talked about some potential slave owning ancestors in my family- Juan de Dios Marrero and his wife Rosa de Rivera from Corozal, Puerto Rico).
  • Delved into the topic of race and its perception after receiving my grandfather's 23andme results. 
May
  • Discussed the 'evolution' the surnames Gustave and Lotten went through in Puerto Rico. 
  • Posted various times about the Finding Your Roots series and its guests. 
  • Began my first series of "An Ancestor's Story Through Records". 
August
  • Discussed the possibility of "Manolo Correa Rivera" being my great grandfather Manuel Correa Rivera in the 1940 Census. 
  • Talked about 23andme's new ability to break down cousins by maternal and paternal sides. 
  • Did some research on the surname Masantini and its potential connection to Tuscany, Italy. 
September
  • Analyzed my results from DNA Tribes. 
  • Categorized and discussed the Antonetti family slaves from Salinas, Puerto Rico. 
  • Posted the second part of my "An Ancestor's Story Through Records" series. 
  • Talked about my chat via telephone with one of my great uncles. 
October
  • Looked at AncestryDNA through the lens of a Puerto Rican. 
November
  • Discovered a sister to my Gustave Lotten ancestor who was born in Santa Isabel, Puerto Rico- would lead to many new discoveries!
  • Probably the best moment in my genealogical year-- discovered documents for a Julienne Malvina Lautin, Eglantine Lautin and Pauline Lautin in Martinique which pretty much coincide with Julianna Balbina Lotten ancestor in Puerto Rico. Learned a lot about Martinique, those ancestors, and what those documents helped show. 
  • Discussed my future plans about learning more about Martinique and my ancestors. 
December
  • Talked about another Gustave Lotten ancestor I was able to find except this time I was able to find a picture of him, his wife and children due to their applications for a passport being ancestry.com. Couldn't believe my luck and considered myself lucky many-a-times. 
  • Analyzed my Ancestry Composition results through the lens of a Puerto Rican. 
  • Discussed my previously unknown connection to the Ashkenazi Jewish population. 
  • Explored my slave roots in Martinique a bit more and how I was able to find Julienne Malvina's birth record. 
  • Explored my slave roots some more but this time focused on the family which owned the Lautin women in Martinique. 
  • Talked a bit about the topic of genetic memory and its correlation to my Martiniquan ancestors. 
  • Lastly, discussed the book Texaco and what I learned from novel. 
In total, I posted 30 times last year which I think is pretty high! Its nice going back and seeing what I felt while discovering those documents and the process I underwent to find what I was looking for. I'm excited for this year to start rolling and for me to start my discoveries!!

Establishing Ashkenazi Connections

In my last post I mentioned that with the new Ancestry Composition you can interactively highlight certain populations in your chromosome by clicking on the group. I provided one with an Ashkenazi separation for myself and a Sub-Sarahan African separation for my grandfather. I want to chat a bit more about the Ashkenazi group and how I've been able to use those chunks of DNA.

When you glance across my DNA, the Ashkenazi chunks only appear three times in "Standard Estimate". The pieces appear on Chromosome 1, Chromosome 4 and Chromosome 9, and with "Speculative Estimate" I receive another piece on Chromosome 7 and a tiny sliver on Chromosome 11. The cool thing about having multiply people tested from my family is that I can rule out who did or didn't give me some of these genes. The two Chromosomes I want to focus on are Chromosome 1 and Chromosome 4. Both of these Ashkenazi genes on those chromosomes I received through my mother and from her father exclusively.
Ashkenazi Connection on Chromosome 1
Here you can see various Chromosome 1 pieces from different people. The first is myself, the second my mother, the third my mother's brother, and the fourth my mother's father. The last entire blue Chromosome 1 is from my Jewish cousin who as you see when compared to myself, my mother and grandfather match us on the same segment. You can also see that I've circled the piece of Ashkenazi gene I received on my Chromosome 1 from my mother and she in turn received it from her father. What's so cool so that this piece of DNA was passed down without really changing, you can see my uncle even received the same piece of DNA on his first Chromosome. Now I want to look at Chromosome 4 where I match a cousin through Ancestry Finder but doesn't have a public account.
Ashkenazi Connection on Chromosome 4 
Here I decided to show it a bit differently by organizing the bars vertically and creating a rectangle horizontally where the Ashkenazi piece is. You can see that my piece of Ashkenazi is a bit longer than my mother's or even grandfather's yet we all inherited that piece on the same spot on Chromosome 4. 

Now, the only thing is trying to figure out how I got that Ashkenazi gene on those Chromosomes. My grandfather's paternal Haplogroup is J1 and my uncle has J1e (for whatever reason, my uncle was placed under J1e) which is found in significant frequencies across the Middle East, being the most frequent in the Arabian peninsula as well as parts of the Caucasus, Sudan and the Horn of Africa. So this Ashkenazi piece could very well be from the male ancestor who passed down the J1 Haplogroup to the Correas. (My maternal male ancestor is Correa but could be something else further back before Spanish surname conventions were adopted. Also I'm not sure whether my family is connected to Antonio de los Reyes Correa from Arecibo, Puerto Rico since my Correa family is located on the South-Eastern part of the island). I have a 4th cousin on 23andme who shares confirmed Correa ancestry with me. When I search her Chromosome 1 or 4 for Ashkenazi ancestry she appears to not have received any on those specific chromosomes, not even on the Speculative level- this could mean two things. It could mean that this piece of Ashkenazi DNA was inherited through the Correa J1 ancestor but wasn't inherited by her. Or it could mean that it came from another family line which she does not connect with. It would take testing other Correa members and people along my maternal paternal family to figure out where these Ashkenazi links come from. 

Also, are they Spanish Inquisition Jewish roots which were passed down to my family or could it be from an actual Eastern European ancestor? These Jewish cousins have ancestry from Germany, Poland, Austria and Lithuania so who knows for sure what the history behind my Ashkenazi pieces are. Hopefully one day I'll be able to look at the Jewish genes and say "You see those pieces of DNA, they came from So-and-so in our family".

A Puerto Rican Look at: Ancestry Composition

This week, after much anticipation and excitement the new version of 23andme's Ancestry Painting was released! This new version, which replaced Ancestry Painting, is now known as Ancestry Composition. Ancestry Painting lacked populations which only used three main populations Asian (from China/Japan), European (which I think were US-European samples), and then African (using Yoruba samples from Africa). The issue with this was that many people for example that got Asian, couldn't differentiate between Native American Asian and East/South Asian. Ancestry Composition on the other hand has 22 populations which includes samples from all around world. Ancestry Composition is still in its infancy, seeing as it how just came out a few days ago, and there will be much to sort out and update. For example, currently Ancestry Composition can only separate West African and North African. This is unfortunate for many African gene-carrying individuals like myself who have no idea where specifically in Africa their genes came from. 23andme did state that the current African cluster will be broken down further but they are running tests to make sure everything will be in order. So without further ado, here is a Puerto Rican look into Ancestry Composition! [Note: results are still changing around, so these numbers and values are only applicable right now. Things may reflect differently later on.]

My Ancestry Composition

So this is who I am; at least as of a few days ago! Percentages have gone up and down compared to the old Ancestry Painting. We see that my European is significantly lower than what it used to be (75%) and my other levels pretty much stayed the same. 16.1% of me is still unassigned which means that as more samples are collected, hopefully this 16% can find a home for itself amongst the colorful bars. As you can see there are a few tabs on top. The first one called "Map View" allows you also to see "Split View" and "Chromosome View" which I'll show in a bit. Split view only works if you have tested either both or one of your parents and Chromosome View is similar in appearance to the old Ancestry Painting. Also you can see a tab called "Global Resolution" which allows you to hone in more on the various populations which are included. Then you see my name, which you can choose to see other people you're sharing with then you see "Standard Estimate". If you click on that tab, you get "Speculative Estimate", "Standard Estimate", and "Conservative Estimate". I'm not too sure on what exactly the defining difference is between them but I'll show you images of Standard and Speculative so you can see how they differ. Now, I'll show you a more in-depth Global Resolution:

My Ancestry Composition- Standard Estimate
Here you can see various populations which can be found in my DNA. There are some interesting and some expected ones. With European you can see that I'm further broken down into Southern and Northern European, and then from there even more. So 20.1% is Iberian which is very expected and 0.5% Italian which is also sorta expected. Then I get 0.2% British and French, which is interesting since in AncestryDNA I get 13% British Isles. Also I want to point out the "Nonspecific Southern European" and "Nonspecific Northern European". These mean that segments of my DNA can be found amongst these groups yet are widely distributed amongst them that they can't pinpoint exactly which subgroup it belongs to. So there could be more British in there somewhere amongst the 19.9% but isn't specific to just the British Isles. Interestingly enough I get Ashkenazi at 0.5%, I've seen cousins in my Ancestry Finder who claim Ashkenazi Jewish roots so I knew somewhere far back I'd have to have some too. It most likely comes from old Spanish Jewish roots or maybe a Eastern European ancestor which is also very possible. Then you can see I have 16.1% Sub-Saharan African which includes all of West, Central, Eastern and Southern Africa- my ancestry from there most likely comes from Western Africa due to the slave trade. Next you can see 11.1% East Asian and Native American, with a 8.6% further divided into Native American- definitely real and most likely from my Taino ancestors (there were also Arawaks, Caribs and even Mayan from Mexico present in Puerto Rico (Mayan through labor trades), then a <0.1% East Asian which I'm guessing is just noise and then you can see 2.5% Nonspecific East Asian and Native American. Lastly, you can see 0.1% which arrives from Northern Africa. My Speculative Estimate tells a little bit of a different story!

My Ancestry Composition- Speculative Estimate
I tend to lean more to this estimate which to me hopefully fits more of my ancestry. I say this because with my Martiniquan ancestors, there should have been some French estimated into my percentages (of course, if no French ever mingled with my ancestors that could be possible as well, but in those times slaves were mistreated as well as raped). I'll let you glance at it, I don't want to make this post too long. You can see some numbers have gone up while others have gone done. But still, 100% me :) Next I'll show you the Split View option which I can see since I've test at least one parent.

My Ancestry Composition- Split View
So here you can see how I've inherited from my mother's and father's side. My mother's side gave me more unassigned as well as much more Sub-Saharan African yet less European. You can also see that the 0.1% North African I receive earlier in my Map View comes from my mother's side of the family. Interestingly, both sides gave me roughly 5-6% East Asian & Native American. Split view is an awesome option for those who might have tested only one parent or wants to figure out which side of the family gave them what. The next few shots will include different "Chromosome View"snapshots.

My Ancestry Composition- Chromosome View
So I'll begin of course with my Standard Estimate of the Chromosome View. As you can there are a ton of nice colors flowing in and out throughout my chromosomes, this is my gene's artwork. Here you can see two bars for each chromosome, except the X which I received one of from my mother. The DNA has also been phased with smoothes out a lot of the colors allowing it to flow easier instead of looking like this (the old Ancestry Painting image with spliced chunks of colors):

My Ancestry Painting 
Now I want to show you my Speculative Estimate with all the previous populations from the Map View. Here is how they change up my DNA colors:

My Ancestry Composition- Speculative Estimate
Here you can see all the further divided colors and what's cool about the new Ancestry Composition is that it's a bit interactive. Meaning that if I want to see where in your DNA a certain population appears you can click on the population and that color becomes isolated while the others fade a bit away allowing you to see those pieces of your genes. For example, I did it twice with my Ashkenazi genes as well as my French and German genes:

My Ancestry Composition- Ashkenazi Population
My Ancestry Composition- French/German Population
What's very interesting is that practically one of my pairs from Chromosome 19 is practically all French/German. Interestingly none of my other family members receive such a huge chunk. Also, you can see the spread out pieces of Ashkenazi genes, one of them on Chromosome 1. Interestingly enough, I match a German/Polish cousin who has Ashkenazi genes on that same chromosome and most likely on that same spot. (I'll probably dedicate another post to that match). Lastly I want to show you my grandfather's Chromosome View with Sub-Saharan African highlighted. He is who has received genes from his 2nd great grandparents from Martinique. You can see he has received a lot of long African segments due to his relatively close ancestry with slaves.

Abuelo's Ancestry Composition- Sub-Saharan African Population
You can also see he has French/German ancestry (I want to point out this is the Speculative View which I feel is more correct to my family history). I'm no expert on DNA and genes but I'm learning a lot from these results about my family and what I carry and hopefully one day pass to my children. You can see that there are a lot of populations/ areas of the world which contribute to who I am and hopefully one day I'll know more stories of my African ancestry as well as my Native and European ancestry. Hopefully soon enough Sub-Saraharan will be divided further but until then I'm happy so far with these results! I'll keep posting about interesting finds with the new Ancestry Composition!

What's In A (sur)Name?

The last four days I spent pouring through Puerto Rico's Civil Registry Birth Records from 1894-1908 from Patillas, Puerto Rico in search of my 2nd great grandmother. 3,003 documents later, I haven't found her. The reason why I decided to bite the bullet and search each document one-by-one is because in other documents where she is mentioned, there a surname which she uses which I have yet to see anywhere else in Puerto Rico (including census records). Which prompted me to write this blog post about the surname and hopefully someone with some knowledge of it or a lead could help me out!

Background: 

Some background about my 2nd great grandmother: Her name is Amalia Rivera Rodriguez/Masantini (she goes back and forth between Rodriguez & Masantini) and she was born about 1898-1901 in what the documents state is Patillas, Puerto Rico. Her father was Cruz Rivera Collazo also from Patillas, Puerto Rico and her mother was Luisa Rodriguez/Masantini from Patillas/Maunabo, Puerto Rico. Amalia married Julio Correa Gustavo/Charles on the 9th of March 1919 in Salinas, Puerto Rico. In her marriage certificate she is mentioned as Amalia Rodriguez (pictured below) and the reason being most likely because her parents were never married. 

9 March 1919 in Salinas, Puerto Rico
In 1910, Amalia Rivera is living with her father Cruz Rivera Collazo in Guardarraya, Patillas, Puerto Rico; her father's martial status is marked as (S): Single. By 1920, Amalia is already living in Rio Jueyes, Salinas, Puerto Rico with her husband. Here, she is mentioned as Masantini (picture below): 

1920 Census in Rio Jueyes, Salinas, Puerto Rico
Months later in March her first son, Manuel Correa Rivera (my great grandfather) was born. On his birth certificate Amalia is mentioned as Rivera and her mother was mentioned as Luisa Masantini. (Pictures below):
1920, Amalia Rivera appears on Manuel's birth certificate
My 3rd great grandmother, Luisa Masantini (sometimes appears as Rodriguez)
The name Masantini doesn't appear again until her third child, Modesta Correa Rivera is born in 1927 when it mentions again Luisa, her mother, as Masantini instead of Rodriguez:

Masantini appears again in 1927

Surname

This surname sounds very Italian/Corsican which is why I'm so interested in it, along with other reasons which I'll discuss shortly. I've search the Puerto Rico Records of Foreign Residents, 1815-1845 and no Masantini or variation of the name appears (I've searched Mazzantini/Mazantini as well). So either the person came in after 1845 or before 1815. Equally, the name has yet to appear anywhere else; even in the 3,003 records I searched not once did a Masantini appear. So I decided to do some research into the last name. I tried searching Masantini along with Puerto Rico and again nothing appeared. I remembered that during one of the "Who Do Think You Are" episodes I believe during the first season they used an Italian surname database to figure out where in Italy there name would be from. Giving it a shot, I decided to search in the database for anyone with the last name Masantini in Italy. To my surprise it appeared! A very small amount of Masantini were found in the Tuscany area of Italy, specifically in the Firenze area. Here are some screenshots of the name appearing in Italy.


Masantini as the red dot (1-5) in Tuscany

The area highlighted where the name appears
Masantini appearing in the Toscana (Tuscan) region, specifically in Firenze
Not wanting to jump the gun and assume that I have Tuscany ancestry running through me, I'll wait until I have further proof to help me identify whether or not I am related to a Masantini family coming from Firenze (also known as Florence in English). Interestingly the name also doesn't appear in America according to this database. There's another reason why I became so interested and it deals with my grandfather's genes.

Genetics

With many 3rd party tools, you can easily use the genetic information you have gotten to find out more. I tested my grandfather with 23andme and posted about results earlier in April. While using things such as Gedmatch.com and getting the BGA analysis I've been noticing some interesting things which I don't know if they are pure coincidences or more pieces to this mystery. In the possible populations mentioned in the BGA analysis were Tuscan along with Italian as well as Spain, when I asked if it was safe to assume there was Tuscan in my grandfather's ancestry he mentioned that it was unlikely to be significant. But could it mean that because my grandfather potentially has some Italian that it appeared none the less though not significantly? Equally in one of the cross sections of European populations, he appears smacked in the middle of the Tuscan & Italian populations. Again I could be overestimating it but no one I've tested in my family from both sides fits so neatly or even as near Tuscan/Italian like he does.

Carlos appears within the Tuscan population
Equally his red dot in the map for Europe appears right over the Tuscan part as well instead of near what I would expect, Spain.

Red Europe dot over Tuscany
Lastly, in the Gedmatch MDLP World-22 Oracle it's interesting to note that in the mixed mode population sharing after Puerto Rican the next possible one is Italian_North and equally as interesting Swiss (which I think could be possibility from German influence on his paternal side- another mystery I'm trying to solve).

Italian_North appearing right after Puerto Rican
I could be overestimating this and connecting false coincidental dots to one another just because I keep seeing the words "Italian" and "Tuscan" appearing left and right; or I could be onto something. So for now I'll settle with the former and consider myself crazy :) There are of course many questions to be asked. Could it be possible that this 'potential' Italian ancestry produce these Italian and Tuscan hits on the genetic side? No one else that I've tested in my family (besides occasionally my mother, of course) gets near to Italy or Tuscany, so why just him? Are the Spanish and Italians genetically different enough for these results to be more than just coincidences? 

Hopefully one day I'll have a solid answer as to why he appears so close to the Italian/Tuscan population and whether or not the "Masantini" family has anything to do with it. So until then I'll hope, dream, imagine and think about all the possible outcomes to this mystery! (And if anyone has an answer or could help; they'll be awesome!)

Ancestry Finder from 23&Me

So stepping away a bit from paper trail ancestry and back to genealogy from 23andme, I decided to take some screen shots from a tool called "Ancestry Finder" and talk a bit about its awesomeness and the results I have. So 23andme has some really cool stuff that you can get dragged into sometimes it seems for hours. Among them besides Relative Finder, Ancestry Painting, Maternal/Paternal Haplogroups and the "My Health" Section there is the Ancestry Finder tool. So the way it works is you fill out a survey telling them where your four grandparents were born (there are some more questions but you only see the countries they list). From those answers, whoever matches you as a cousin will show up in where ever they match you along your chromosomes and then show the countries where the grandparents were born. What's real cool about it is that you can switch around controls in the advanced options to what you'll like to see. For example, here is my Ancestry Finder set to: "5cm" Minimum Segment Size and 4 Grandparents born in the same country.

My results for Ancestry Finder

I added the countries over the bars to show where the grandparents were from. I was VERY surprised by the results; I matched people with grandparents born in Cuba, Columbia, Mexico, Ireland, Spain, Portugal, Lithuania, Russia, and the U.K. This doesn't mean that you have direct ancestors from there but that someone centuries ago from in your ancestry could have moved there, had extended family there, etc.. The ones that surprised me the most were ones like Lithuania and Russia! These are unexpected I would say for me being that my family is from Puerto Rico and you don't really hear about these groups having descendants in Puerto Rico.I do match people from Puerto Rico but since I didn't set it to show matches from the "US" they didn't show up.

You can also change around the advanced settings to 1+, 2+, 3+, born in the same country; to show matches from the US, Canada, Australia, New Zealand & South Africa; to show public segments; indicate segments people have marked to be of Ashkenazi Jewish ancestry and the minimum segment size.

I also took screen shots of my grandmother's and great grandfather's Ancestry Finders to show the different results they got. Here they are below:

Grandmother's Ancestry Results

Great Grandfahter's Ancestry Finder results

You can see how some segments my grandmother inherited from her father while other segments don't show up on his. What's really interesting is when segments overlap one another such as where on my great grandfather's Ireland, U.K., Portugal and Switzerland matches overlap. I wonder if they all/most of them share some same common ancestor? Its really cool to play around with the settings and see what countries you have distant cousins in.

I hope I can prove some paper trail matches with these cousins one day!

The Magic of Genes

Joining 23&me at the age of 18 opened my mind to A LOT, not just about genealogy, ancestry, genes and everything in between but it allowed me to take part and become a member of a community with genealogy buffs like myself. Logging on and seeing how some people have reached ancestors born in the 16th century pushed me to want to get to that level! I chatted with one very friendly and well informed cousin on the website who taught me some of the ropes of what all this meant and more. I was able to find out things like my Maternal and Paternal Haplogroups, my 'ancestry painting' and 'connect' to, at this most currently over 550, relatives. This relative introduced me to FamilySearch, a website which actually contains records before 1910 for Puerto Rico. How ecstatic and ready I was to start searching for records! Though at first I was a bit hesitant because it required me to search documents one by one (luckily some have indexes), I bit the bullet and started searching for ancestors and boy have I found a ton!!

Going back to my 23andme results, I got back some interesting information. My paternal haplogroup, which is passed down through the Y chromosome along the males in the family (son, father, grandfather, etc.) came back as I2a1*. Haplogroup I is surprisingly most common amongst Southern Europeans such as Balkans and Sardinians with 40% of Sardinian men belonging to this group. Yet my specific branch/subgroup (I2a1*) is "believed it originate high in the Pyrenees, the string of mountains that separates Spain from France. About 12,000 years ago, as temperatures warmed and glaciers retreated, men bearing I2a1 expanded into Spain, France, and nearby Mediterranean Islands." (23andme website). So this would mean that centuries ago, one of my paternal ancestors came from around that area of Europe. Pictured below is the screen shot for members of the I2a1* haplogroup and its concentration around Europe.

I2a1* Paternal Haplogroup passed down only to men

My maternal haplogroup, which is passed down from mothers to both sons and daughters, was very interesting. It came back as C1b4, which arrived from Asia into the Americas and is most common amongst Native Americans. Wanting to learn more I began to research this haplogroup and found that it was one of the common Haplogroups among the Taíno people of Puerto Rico!! This would mean that centuries ago a woman along my maternal line was most likely a native from either Puerto Rico or a nearby island. Due to the fact that many Spaniards arrived without woman on their conquest for new lands, they reproduced with the natives and/or slaves giving people such as myself these Haplogroups. Pictured below is the screen shot for members of the C1b4 haplogroup and its concentration around Asia as well as the Americas.

C1b4, Maternal Haplogroup passed down by mothers

All this information was fascinating, something I had seen on a TV show actually was real and capable for the average person to buy, use and understand! My ancestry painting, which has changed a bit from when I first tested, shows that I am (approximating of course): 75% European, 15% African, and 9% Asian. (As you saw from my results, Asian doesn't necessarily mean one my grandparents was Chinese, Indian, etc but can also be natives who carry those genes from their ancestors from the Asian continent and moved into the Americas.

My genealogical search was taking a new technological turn and with FamilySearch records in my hand, my branches on my tree were going to stretch a bit farther into the past!
