Re: I wish to hire a DNA analyst to interpret the results of a Big Y-700 FTDNA Sample #dna
The Big-Y is for granular assignment of your particular Y mutations place in the Y-tree. It can tell you general migrations and locations of the populations who had those same mutations or derivations of same. If you are trying to identify the subject's original surname, the Big Y test may not help. Ashkenazi only took surnames in the last 200 years or so. The Y-DNA tests, including the Big Y, look back at DNA from 2000 years ago and more... Finding a match in a more recent time frame is a huge long shot since the database of samples is pretty small. You should use the at-DNA (Family Finder) test which will give you matches who may be able to shed light on related surnames and locations within a genealogical time frame of about 6 generations.
