I’m sorry, but I have nothing more on Isaac Beard. The earliest record I have for him is in 1850, in Fayette county, Tennessee. It appears that the family moved to Arkansas sometime during 1858 and remained in the state until at least the 1880’s. He was 75 in the 1880 Arkansas census, so I imagine that he died there. The 1880 census lists his father as being born in Ireland.
When I first found a record of Isaac, he was in his middle forties and no longer with his father‘s family. There could very well be a link between our families, but since I don’t have Isaac’s parent’s names, or any of his sibling’s names, I really can’t say. (Note: Your email address is no longer valid.)
