There are numerous ways this Finn-Volga-Uralic DNA might have shown as a match. First, as pointed out by another, this result means some of your DNA matches some of the DNA of a certain percentage of people from that region dating back possibly thousands of years. Second, populations have migrated and intermingled for centuries. Many if not most of the present day central Europeans and their descendents from other areas more recently inhabited, have mixed with migrating populations from Russia (and the broader Volga-Ural). This is well-known and documented, and a quick search on the internet will bring up many authoritative articles about this. Even Celts were known to have originated as a distinctive clan from the Central European area near Germany-Austria, and were probably intermingled at some point(s) along with many other clans who remained or emigrated to different areas. Many Germans from the Rhineland and Bohemia emigrated to the US, both farmers and miners at different times. And there were further migrations due to political (eg, 1848) and religious intolerance. Of further interest is that many of those with DNA matched to the central European and Volga-Uralic areas share a Middle Eastern origin. There is also a more recent migration that is believed to be the origin of the Ashkenazi Jews in central Europe and further east. The moment we think it is a simple story, it is time to do another search; it is just not simple: wars, famine, pestilence and even climate change have had dramatic effects on migration and the intermingling of different clans, and this just begins to explain the complexities of defining ancestry in this age. My own "mix" is 24% British Isles, 64% Central European, 10% Finn/Volga-Ural, but it would be difficult to say exactly what came from where. Perhaps the DNA matches are the best "look", after all, since that is where the folks I match tend to be from. The question then becomes: when?
