When I first tested, I had this naive hope that I'd get some clues as
to where my father's family lived prior to immigrating to the United
States. No such luck! All anyone (Ancestry, 23, MH, FTDNA) can tell me
is that I'm Jewish which I already kinda knew.
The problem with the different sample populations is that records are
sparse in most countries. The members of the sample may think their
ancestors lived in the same country for the last 500 years, but
generally no proof other than family lore. Ancestry even says that they
use family trees as an input, and we know how well-documented a lot of
those are. So for non-Jews, it's a best guess estimate that will
continue to evolve as Ancestry et al refine their samples.
