I began my DNA based research with Ancestry.Com’s Y-DNA. Initially, I was disappointed because the closest match to me was one where our Most Recent Common Ancestor (MRCA) was ten generations away. He had his tree going back seven generations, not quite enough. Sigh.
My Y-DNA Lineage from Ancestry.Com
After several months another person matched with me. This time our MRCA was supposedly only three generations away. Very cool. This was a line I could possibly follow. I figured, If I could follow his tree up the seven generations that he had and then followed all of the male descendants down, I might find one that was in the right place at the right time to be my paternal father. I’ve gone up four or five generations and followed all of the male descendants; I still haven’t figured a potential candidate. That is to say no one at the right place at the right time.
Then I was talking to a friend is is extremely knowledgable about DNA testing and results. He was telling me that the person I was looking at might be much further away. He and I matched 30 of 30 overlapping markers. I had taken a Y-46 marker test and he had taken a Y-33 marker test. My friend indicated he has seen many cases where 30-40 markers were matched up fine but when the test was expanded to more markers the matches fell apart and the MRCA jumped much higher. I will need to see if my close match there will take an expanded test (even if I pay for it).
My Wife’s Y-DNA – Ancestry
My wife’s brother’s ancestry per Y-DNA from Amazon.Com
Of course my wife couldn’t supply a Y-DNA sample. So far, we have had one of our biggest brick walls on her paternal side. I had really hoped that DNA could open a gap. We asked one of her her brothers to help and he supplied the sample. Of course, we had to explain our actions and desires several times to my wife’s mother who thought we were in some way suggesting she had slept with the milkman or some such thing. On my brother-in-law’s test we had an immediate hit on Ancestry. All the markers but one matched and Ancestry suggested a MRCA at six generations.
We only have four generations on my wife’s paternal line. The potential matching cousin has seven generations identified on his paternal side. So, if we can’t trace up to his tree, possibly we can trace down from his tree to a common ancestor. I have a lot of work to do to do that tracing and see if I can trace from his top person back down to find my wife’s ancestor.
I used my Ancestry Y-DNA test results and purchased a transfer kit from my.familyTreeDNA.com to transfer my results to their system.
I emailed the closest hit to my DNA (89% likelihood a common ancestor in 8 generations). No answer. I emailed him again, no answer. Then I did some on-line research on him, it appears that he died. I found someone who appeared to be his sister and emailed her. No response. Again frustration. My second closest hit was to the same person that I had matched before on Ancestry ten generations from a MRCA (88.85% for a match in 8 generations in the My Family Tree DNA parlance.)
I have not had any new matches or other contacts on my Y-DNA. It seems like no one is doing the Y-DNA test any longer, or at least it appears to have dropped significantly in favor of autosomal DNA testing.
My Autosomal Results
I was part of the Beta testing for Ancestry.Com’s autosomal testing. The “ethnicity estimate” didn’t have any surprises. I’ve received quite a few “matches” on Ancestry, but they don’t tell you how or where the match occurred. All my matches there have been “possible range 4th to 6th cousins and nothing of significance has been found there.
I was attending a Genealogy Special Interest Group meeting of the Genealogy Society of Cobb County Georgia and was talking with the resident DNA Expert. He suggested that I do autosomal testing of both myself and my mother, who is still living. I thought to myself, “Duh” or maybe I actually used my out loud voice. In any event, have both myself and my mother’s DNA in the same system would conclusively prove a connection went through her or through my unknown father. If a person matches on me and my mother, the linkage must be through her. If a person matches on me and NOT my mother, the connection must be through my unknown father.
I decided to go with 23 & Me because they provided the best price. They were actually low enough in price that I could get the testing there and transfer the results to Family Tree DNA as a lower price than testing only Family Tree DNA. (That isn’t the case currently.) Besides, with 23 & Me I would receive health risks results. (That isn’t the case currently either because the government thinks that telling people about possible risks is somehow practicing medicine. New customers will need to wait until 23 & Me’s appeal makes it through the court system.)
The results were amazing. Immediately, I connected with someone that matched with both my mother and me. Because of that connection I was able to sort out some problems I had tracing my 2nd great grandmother (my mother’s mother’s mother’s mother). I was also able to push that line back another generation. I wrote about it at length at http://dontaylorgenealogy.com/2013/08/23-me-blackhurst-line-exploration.html/
After that initial success frustration again. The next three matches matched against me and not my mother, so I knew they were matches against my unknown father. I contacted them and no responses. It is really frustrating when there is no response from people.
I learned about another service that is free called GEDMatch.com. It is a very cool site and it is free. They give instructions on how to export your autosomal DNA test results from Ancestry.Com, Family Tree DNA, and 23&Me and import the results into their system. Their system is agonizingly slow as they take a few weeks to process your data and then eventually it is populated into their system. As I mentioned, it is free, so you really can’t complain about the speed. After a few weeks your results become available and they are really nicely portrayed. You can do one to one matches, one to many matches and actually see which chromosome you match on and how long of a segment matches. It gives you the ability to see exactly what is going on. Because I’ve uploaded both mine and my mother’s results I can tell easily if a match is on my maternal or paternal side. I really like the system. Contact with potential cousins is through regular email so it is easy to keep track of correspondence with people on different systems.
More recently I have had several matches with people on my unknown father’s side. The wonderful people have shared their trees with me and I will try bringing their information into my “Notional Tree” as cousins in a potential relationship. We’ll see what it may find.
I think that in the end, DNA is a helpful tool. It has the potential to break down some brick walls, like it did for my Blackhurst tree. However, it is not likely to magically solve a problem or give answers to difficult questions.
In my opinion, the best system I’ve used for analysis of autosomal data has been GEDMatch. I really like what they are doing. I noticed that today their website is down due to a server failure. That is really sad. Once their system is back up I will definitely send them a donation to help them keep their system operational.
Because GEDMatch doesn’t test themselves, rather they allow you to upload from many different testing results, it really doesn’t matter which of the many autosomal DNA testing companies you use. I think that MyFTDNA has been the best for Y-DNA.
