I am searching for information on descendants of William and Thomas Wertman and possibly a Thomas Camp. They are descendants of Rosannah CHRIST and John Wertman. Sophia Christ, possibly known as Sallie, was married to George Adam Ritter. These two were sisters. Both were in Northumberland co. Their brother John Christ/Crist was in Lycoming co, and had a large family. Their sister was Susannah Christ/Crist who married a John Smith. I have a lot on John Crist who married Catharine Snyder, but very little on Susannah and John Smith. All are listed in a partition record in Hancock co OH in 1849. I suspect John Crist died in 1850. Any help on these would be appreciated. Margaret Crist Calvin.
