Casey, 63cM is very close to what we'd expect with a 3rd cousin, but with the randomness of atDNA, almost anything is possible. What I'd do is look on GEDmatch for others who match on this segment, and work with them. A 63cM segment is probably a combination of segments from more distant ancestors. So look for those more distant ancestor with other Matches on this segment. When you find them with a Match, you'll know what line beyond the Common Ancestor the DNA came from and you'll have a better picture of where Match #1 fits in. Be open to any possibility.... Also look for Common Ancestors with others who match on the other shared segments with Match #1.

I match #2 on the same segment of chromosome 9 - 25cM/4750 SNPs. FTDNA guesses match #1 to be 2nd-4th cousin and #2 to be 3rd-5th. My 4x great-grandmother has the same surname as: Match #2 - 3x great-grandmother Match #1 - 2x great-grandmother thru 5x great-grandfather All lived in the same/neighboring counties at the same time. Best case/most closely related scenario - all 3 of us share common 5x great-grandparents making us all 6th cousins. I am confident in match #1's 5x great-grandparents. My 4x great-grandmother is the right age and correct name to possibly fit here as daughter of match 1's 5x greats but it's just a guess. Match #2's fit is a total guess - there is a son of the 5x greats who would be of correct age to parent the 3x great-grandmother, but she could easily be a further match than this. My question is can a 63cM matching segment actually not be closer related than 6th cousins?? Match #1 & I share a total of 80cM while match #2 & I total 43.8 - all the other segments under 3cM. Thanks! Casey
