I was finally able to get the results of my father's DNA test, and it turns out he is in haplogroup I2a2b I-L38.
I found that haplogroup in a Brooks one name study at FTDNA
There are only 4 entries under I2a2b with the group of I-L38 one of the entries is a copy, one of them has an unknown father, and the other is the father of the one with the copy. (sorry if that sounded confusing)
Should I assume that my Brooks line is descended from that line?
I'm fairly certain that line is one of the lines discussed in this book http://babel.hathitrust.org/cgi/pt?id=wu.89062872569;view=1up;seq=7 Brooks and kindred families
I have made some semi-educated guesses from other sources and arrived at the same lineage as the most likely for my family, but there are gaps where I made some leaps just to get the connection going.
Have any of you heard of false lines coming from DNA results?
I'm very excited about this bit of confirmation, but I don't want to go too far with it and assume it is concrete.
Any opinions would be helpful especially if I'm heading the wrong way.
Just converted my grandfather's test as well he is the same group. I wish the Ancestry test gave more comprehensive results.
