Darrell, if your John Holt came from Pennsylvania there is a good probability he descends from the line of Immigrant Henry Holt and his wife Dorcas Armstrong. As far as known now, they had two male descendants, Henry b c1731, and Thomas b Aug 1733 and christened in Christ Church (Episcopalian) in Philadelphia Sept. 27, 1733. Both sons had descendants named John as did some of their descendants. They were very prominant in Mifflin and Centre Counties Pennsylvania. Henry disappeared c1735 and Dorcas married Arthur Buchanan in New Jersey in 1738 and had five children. Dorcas had six descendants serve in the Revolution. Several folks have used Thomas's son John as a means of getting into the Daughters of the American Revolution organization. An excellent source of well documented genealogy to the present. Also, If you think it will help, I can provide you with some data. Regards, Bob Holt, in Arizona
