I recently "met" a Newbrough cousin over the phone and he sent me a publication he has been putting together for sometime. It traces the Newbrough line from John W. Newbrough (1700-1735). This guy came from England to Chester Co. PA and descendants have gone to WV, Ohio, Iowa and other places. While not all lines are completed, and I haven't verified sources, it has served as a great starting point. He has a newer version coming out later this year which will be indexed. But if you have specific names/dates, I'd be happy to try to look them up in my copy.
