I know that Hannah / Anna, wife of Johann Conrad sometimes becomes confused with Hannah / Anna, wife of Andrew. Do you have a copy of Anna's will from 1820? Bob Hesser told me that it was assumed that Johann's widow, Hanna died abt. 1820, since that is when she disappeared from the Loudoun tax list. There is still a Hanna on the Waterford, Loudoun census in 1820, but not sure which month. Since it only says age 45+, that does not narrow it down much. I would love to see a copy of what you have for Hannah? Wonder if that or anything you have lists her children?
