Thanks for answering my previous message. I have found a link to some of them-trying to tie it together. Some of the Morgan-Cass-Warren-McDonough Gibsons are from Pa.to Greene Co.,Ohio to Illinois. Some down to Tenn., then to Ill. I am finding connections am hoping someone is researching Thomas b. 1774 Pa. Samuel (son) b.1804 -John b.abt. 1797 Pa.-Andrew son. Cullen Gibson was the son of Samuel. I believe David Gibson was the son of John. All in Ill. Any one want to jump in?? Thanks again, Victoria Gibson
