OOf, that's pretty good! Thing is, records were meticulously kept for the well to do, but not necessarily the peasants! So your DNA might show your entire family never left a certain area (like my father in law - his DNA shows him as absolutely pure LONDON!) but the records don't go that far back. And if you were a servant or a pauper, chances were you never even got a headstone. It's so fascinating! I'd love to get my DNA done but I'm a bit worried about the whole data thing.
