I'm sure you know, but there are many Woods in Chester county, and a slew named John...so, it might be easier to approach it from what I assume is the other end. By that I mean I'm theorizing that you have a John Wood in your line...if so, who did he marry? When? What documentation do you have for him?.....armed with a bit more info, we might be able to find him among all the other John Woods. Sandra " To all Wood researchers:? Who is this John Wood, found in the 1820 census in London Grove with one adult male over 45, one 26-45, 3 males from 16-26?"
