I recently obtained new info that contradicts the long & widespread belief that Abigail Elizabeth Powell Duvall (wife of Alexander) died in 1842. The incorrect date of death was originally based on the "Alex. Duvall Bible of 1870."This Family Bible contains written entries that are riddled with errors and was obviously written by someone after the era it was said to have taken place in. I would gladly discuss this topic with anyone who is interested in this subject.
I base my conclusion that ABIGAIL ELIZ. died between 1820 & 1829 on the following two facts:
1) She does not appear in the 1830 or 1840 Censuses. 2) At the time of her husband Alexander's death in 1840, he was remarried to a woman named MARIA.This info was obtained from land records located in Fayette Co., Pa. Courthouse.I will provide the citations and transcriptions to anyone that is interested.
