I've done Y-DNA (Big Y) and mtDNA (full sequence) tests and the results were quite depressing. The closest Y-DNA match has an MRCA 2-3000 years ago. My mtDNA is unclassified H, nothing close to a match. And the more depressing because the reason for doing the testing was that my paternal and maternal lines are my two brickwalls, both at the second great level. On the maternal side I identified a couple of potentials, but couldn't find any sources to discriminate between them. So I started trying to trace descendants of the two women and found only one option, the children of a woman who lived in France (she died about ten years ago). As an aside, it's interesting how easy it was tracing to her compared to finding her living children. So one of the children agreed to testing, the results are due in a couple of weeks. But on Friday I got a zero genetic difference match on the full sequence. And it turns out the match is a French genealogist, who has identified our common ancestor! I'm so happy ;)
