I have done very little with my Mother's FF test but last week an e-mail from a match (I'll call her #1) inspired me to start searching for the common ancestor. That search produced a second (#2) and closer match (new on November 4th) for my mother. Match #1 has also tested her mother, son, and several other relatives; however, she matches my mother and match #2 on the X chromosome whereas the her mother does not, indicating that the X match came from her father's side.. (The other relatives, including her sister, don't match at all.) I wrote to Match #2 because she has ancestors in Oxfordshire just as we do, and her reply identified at least one ancestral line. I am now waiting to hear exactly how she is related to my mother's 3rd great grandmother Mary Eley. FTDNA lists them as 2nd-4th cousins--probably third, but she does not descend from Mary so the relationship will be somewhat more distant. There is no question about this relationship, though; our Eley line is well-documented back to the 1600s in Oxfordshire. The question is: do we have other lines in common which make this relationship appear closer than it is? Mary Eley passed her X chromosome to her son John Lindsey, but since it did not descend to his son (my mother's grandfather), there must be at least one more common line of descent unless the X matches lie within a pseudoautosomal region. Can anyone tell me the exact locations of PAR1, PAR2, and PAR3? The matches are at the centromere, but I don't know whether they extend beyond that region. Match 1: 53915099-67881743 Match 2: 51333207-67881743 I have checked every X match on the first two pages of X matches and discovered 14 more with the same end point. Of the four others with different end points, two had the same start point as Match #1. A third had the same start point as one of the group of 16, and the fourth, like Match 2, had a unique (so far) start point. Another related question--how does one decide, in the absence of paper evidence, that the match is actually on the same chromosome when either the start or end point doesn't match exactly or when the matching regions overlap but neither the start nor end point matches? Last question--does anyone know when FTDNA plans to make the new FF tools available? Lindsey
