I am trying to link Isaac Updegraft married to Susannah Friend to my ggrandfather Thomas b. 1821 in Ohio. Thomas was married to Sarah Oberholtzer and Amanda Caldwell. I have one lead that says that there was a possibility Simon Updegraft was their father. Also an Elizabeth Updegraft m. Jacob Friend maybe Isaac and Thomas' sister. I have info on Thomas and having been trying for years to locate his parents..
