Cathy, Have not much info on the Dingman family. I just found you message as my email has changed so often sense I posted the former message. I do know my Dingman family was in New York pre Rev. war and some stayed and some left to Canada. Mine went to Canada. I have no info on the ones that stayed but there is lots of others looking for the Dingmans as they were a well recorded family.
Sorry I can't help right not. Trying to figure out how to change my email so I can update this info
