In doing so, he computed ... WebmtDNA mutates very slowly so a match with a genetic distance of 0 can still go back hundreds of years. It's more useful for confirming a link on your maternal line based on records you already have. If those mtDNA matches took an autosomal test and don't match you at all there, the connection is so far back it's probably not worth looking into. 5. clive tanner wyatts hall green
