Question
I just received the Family tree Y DNA results from my Uncle's DNA test. Of the 58 values on his Y-DNA - Standard Y-STR he matches 51 exactly with another person the other 7 are:
DYS19 other person 15 uncle's 14
DYS448 other person 18 uncle's 19
DYS464 other person 14-15-17-17 uncle's 15-15-17-17
YCAII other person 19-23 uncle's 19-21
DYS576 other person 20 uncle's 19
DYS444 other person 13 uncle's 12
DYS446 other person 12 uncle's 13

In the family trees of both families it shows they are descended 9 generations back from Francisco Reynoso. Do these results confirm that connection given that baptism and marriage dispensation records back it up?

Thank you in advance for educating me on DNA interpretation.

I am not an expert, but I have some experience with these tests. I think 7/58 differences is a lot, but there may have been 3 mutations on one branch and 4 on the other over those nine generations.
I don't think the results confirm the connection, but given the records, I would say the results suggest the connection.

Check out Gary Felix's Mexican DNA page:

It may take a while to open, but at the very end you can see the section of Y-DNA founders, with examples of families with a common ancestor probaly 8-12 generations away. Some of the branches have at most 3-4 differences, not 7.

I think in order to confirm the connection, you need to compare with more samples from other branches of the family and see if you both separately are a better match to the new samples. Also, how come you tested for 58 markers? I thought FTDNA went from 37 to 67. Did the other family just tested for 58?

In my family one of our samples has 3 differences with another one, and our common ancestor is just 3-4 generations away. However, when comparing with a third sample from another branch, each of us has only one or two differences with the third sample (67 markers compared in one case).

I'm sure Armando and other members will have more to say regarding your sample.

Thanks Victoriano, I will check out that website. The results came this morning and I'm still trying to figure them out. The test is a Y67 and when I compare it to other Y67 tests they all only have 58 values in the Y-DNA STR markers, which is just another indication that I have a lot to learn about how to read these DNA tests.

What company did you order your DNA test from? What were the costs? Both my parents did a DNA test through Ancestry.com, but it only shows where they came from. I don't believe they received the actual codes/raw data.

Thanks.
