Before there were so many SNPs discovered, Ken Nordtvedt used to study haplotypes made up of a small subset of markers that FTDNA tested. I think he looked for the most common haplotype in a given area, which would suggest that it originated there.

The problem is that such haplotype old enough to form a likely haplogroups originated so long ago that the person's descendants would have migrated all over Europe, usually in a western direction, before one emigrated to America.

I think SNPs have been found for most, if not all, of the categories, so it is best to take haplogroup tests. However, I do not know if any of the subgroups are confined enough to be useful in identifying ancestral origins. For the most part, DNA testing can identify only continental origins.
