Mother's maiden name is Lewin. Came from England, possibly ancestors in Wales, as mtDNA comes out J2a1a1. All that maps and data I've seen don't really explain it, but I get the impression this haplogroup may be neolithic in the British Isles?

For reference, my Y DNA is R-U106 R L48, per, which they call Germanic, and/or explain as the Anglo Saxon line in the Isles. This makes sense to me; the MtDNA less so. Also, my Uncle, on my mother's side, was Y DNA I2b, which has apparently been refined to I2-S2361. So my Mother's dad was likely also "Germanic?"
