Our Owens match contacted me yesterday. I found out that I was comparing with the exact same kit at GEDmatch as the one at FTDNA. So there was a 6 cM difference in the segment my Aunt shared with this match on chromosome 19. It could have something to do with the fact this kit was a transfer from AncestryDNA to Family Finder at FTDNA?
I have no idea why the results look so different at GEDmatch? I don't know if FTDNA is more accurate or GEDmatch? I just know the results don't match. If GEDmatch is less accurate than the testing companies than it may not be a good place to compare AncestryDNA results? It may be better to transfer your results to FTDNA and compare there. Although it may be that errors occur when raw data is uploaded to FTDNA? However I have compared with other transferred kits and don't see any unusual results?
Like I said before there are always slight differences in the cM numbers at GEDmatch. If anyone else has seen a cM difference of 5 or more on a segment please post a comment. I'm curious about how often this happens?
