I am searching for information on John Davidson b, Abt. 1759 and died Abt.1843 in Pennsylvania.(May have been in Revolutionary War). He had at least one son named Samuel I. Davidson, also born in Union County, Pennsylvania in Sept. 1800. If anyone has information on these two, I would love to know about it. In general, I would like to know the name of John's wife and other children. Thank You Marsha BryMar4950@aol.com
