{LosCuellar.com.mx 203} Cita de Somos Primos: Diego Trevino Y-DNA

Diego Trevino Y-DNA By Crispin Rendon Crispin.Rendon@gmail.com I have posted online a report on the Y-DNA of Diego Trevino. http://home.earthlink.net/~shharmembers/MikeAyalaYDNA.pdf

Just about anyone with roots from the Mexican states of Tamaulipas, Nuevo Leon or Coahuila had some fantastic news last year. Most have not heard and probably would wonder what the big deal is if they did. The news is we now know something about the Y-DNA of Diego Trevino. "Who is this Diego Trevino and why all the fuss?" Diego Trevino spouse of Beatriz Quintanilla is the 10th great grandfather of Mike Ayala. This couple, Diego and Beatriz, are ancestors not only to Mike but also to, you guessed it, just about everyone with roots from Tamaulipas, Nuevo Leon or Coahuila. We have Mike to thank for being one of a growing number of people who are using a new tool to learn about their ancestors. This is the moment to turn on some fanfare on your iPod and turn to page three of this article to see Mike Ayala's "67 Marker Y-DNA" test results! Perhaps I should warn you first that this new tool for doing family history is totally different from "old school" family history discoveries. Traditional family history discovery involves finding old documents that tells you something you did not know about your ancestor. This new YDNA family history method is scientific. Well you have been warned so go ahead and see for yourself that the big discovery is just a bunch of numbers. You might ask, "Why has Mike gone to all this trouble and expense for a page of numbers?" These numbers identify his Y-DNA as haplogroup E, sub-group E1B1, subclade E1b1b1. You never would have learned that from looking at old documents! I descend from Diego and Beatriz dozens of ways and that is why I think learning a bit more about them is wonderful. Unfortunately my Y-DNA test results tell me nothing about Diego. Mike descends from Diego and Beatriz 183 ways. One and only one of those ways allow us to link his test results to Diego Trevino. I have included an illustration on page 4 that I call a stairway chart to show the Y-DNA relationship between Mike and Diego. Find Miguel (Mike's given name) Ayala as number one on the chart sandwiched between his parents. Climbing the generational staircase you find fathers as sons sandwiched between the next generations all the way to the top of the staircase. When I told fellow family historian, Irma Cantu, that I wanted to write this article, to her credit the first thing she said is you have to give sources. Scientists explain their methods so that others can replicate their results. Family historians give sources for the same reason. What you want to see in family research are primary source documents. They are the gold standard in family research. Mike was all for this and was quick to point out that he had not done all the research himself. Esther Arredondo Herold had cleared a brick wall for him at generation five. Esther's name comes up time and again as someone willing to share family history research. She liked my idea and was eager to help. Collaborations rarely work without a lot of patience. This was not a problem working with Esther and Mike. I had an emailed report with sources (LDS film numbers) from Esther almost immediately. Mike responded to my email questions the same day. We had one setback. The DNA lab wanted more time to rerun Mike's expanded 67 Marker test. I used the time to see if I could replicate Mike and Esther's results. I entered all the information used to create the staircase chart into a PAF file. Starting with Mike's PAF record I added all the sources I found into the note fields. Many times family history evidence linking generations is found in the records of ancestral siblings so I included the siblings in the file. The same file was used to create the report on page 5 of this article. I want to thank Mika Ayala for allowing me to publish his test results and research, Esther Arredondo Herold for all of her help and Gary Felix for his wonderful Mexican Surname web site.    http://garyfelix.tripod.com/index63.htm
