I have oldest daughter Sarah born about 1821 which would make James about 16 or 17 when she was born. I know he was not on the 1850 census and I don't think he was on the 1840 census either. I heard a story at one time that he had gone to Arkansas with Elizabeth's brothers and was murdered or involved in a murder but have never been able to verify that. My ancestor James Albert Poff was living in Arkansas with Elizabeth's brother John on the 1860 census.
