FWIW, These early colonial North American surnames have I1-T2 lines: Bradberry, Foster, Buie, Whitehead, Moore, Morris. So far as I now know, they are all southern (Virginia or Maryland) and none are "prominent". Also, I have no solid links across the "pond", but Foster and Buie may be Scots, Bradberry and Whitehead northern English, and Moore associated with Essex. I stress the "may". Brent Bradberry
