One of the male descendants of my family Y-DNA tested at Ancestry.com and his haplogroup was determined to be R1b. I’ll call him Harry. And another male descendant, presumed to be of the same family (same surnames, migration pattern, geographic locations), Y-DNA tested at FTDNA and was determined to be I1. I’ll call him Arthur. This was quite surprising. My paternal line descends from the R1b male line. So I found another male descendant. I’ll call him Dave. On paper Harry (b. 1940) and Dave (b. 1951) are 8th generation, from 2 brothers of the same father. This week I received the Y-DNA results for Dave from Ancestry.com. He was determined to be R1b. So this would indicate that Harry and Dave are likely direct descendants, but Arthur has some other relationship that gave him the same surname.
My confusion is that Ancestry provided me a list of several matches and near matches. None of the surnames match our surname and Harry wasn’t identified in the list even though he is in the Ancestry database. So I compared the results side-by-side and found that Harry reported on 42 markers, Dave reported on 43 markers. Of the 42 markers they reported in common, there are 16 with differing values.
They definitely come from the same common ancestor and we know who that is: Burlingham Rudd. We know where he came from: Norfolk, England. And we know when he got to South Carolina: 1729.
Can someone offer some insight about how this happens? Frankly, it has made me very skeptical of the process. Here is a list of the markers. Thanks, LindaRudd@aol.com
