Re: I wish to hire a DNA analyst to interpret the results of a Big Y-700 FTDNA Sample #dna

It * IS * possible to limit the number of Y-DNA markers that you look
for matches on, even if 700 were tested.  You can limit it to 35
markers, 67 markers, or 111 markers, and have a much better chance of
finding surname matches.

And yes, it is a good idea to also use the Family Finder test as well,
along with the Y-DNA test.

The Big-Y is for granular assignment of your particular Y mutations

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.
