Last November, before this separate mtDNA message board was created, I posted a query on the general DNA research board about using mtdna results from the basic mtdna test offered by FTDNA which had been sold as combination sale price for family finder and the basic mtdna tests. I had received back 900 matches for this basic mtdna test, telling me I was H Haplogroup. I posed the question of what to do with this result, particularly since 95% of those testing at FTDNA appear not to have gedcoms posted there and it is almost impossible to find shared ancestors on the site (when I have on the FTDNA family finder test, we have almost always switched to our ancestry.com trees to look for common family lines). The response I got was very helpful and said that H Haplogroup was the most common European Haplogroup and that the basic test would not provide any insight into genealogical relationships, just massive human migrations etc. That I would need to take the full sequence, FMS, test to get any genealogical useful matches. I did. Just got results back.
Now I am H3 (plus a string of numbers) and my matching rate is 15 people, of whom only two have gedcoms and none of them appear to have any connections to my maternal line which involves a "brick wall" 1871 Irish immigrant to the US, born in 1863 with an extremely common Irish surname. Given prior extremely poor response rate to emails at FTDNA (if you think private trees at ancestry.com are a problem, FTDNA is many times worse with few trees at all, no documents at all)I am sort of reluctant to start trying to contact the other 13, particularly since the 2 with gedcoms don't appear related at all.
So...experts on mtdna results, tell me what to do next. Just file this away? Are these 15 matches really solid (i.e. genealogically timeframe) or more of the ancient human migration data?
