I have noticed that some (but not all) of the Webster men who have had their Y DNA tested, and have published the results on the Internet, have turned out to be in haplogroup J, and more precisely, subhaplogroup J1. J1 is sometimes found in the British Isles, but it is rare. Has anyone studied the J1 results to determine when the Webster J1 might have arrived in Britain? Neolithic, Roman period, or later?
