Hi, I think we may be talking about two different Joel Browns. My information on this Brown family (Samuel Brown through his great-grandchildren in Joel's line) comes from a family bible (in my possession)that was started by Joel Brown in 1799. The early information (such as Joel's parentage) was written after it happened, but the other generations were written at the time of the event. I've researched the information in the bible thoroughly and have never proven it wrong. I've found no reason to question the names Joel put down as his parents. Their obituaries are also pasted in the bible. One of Samuel's established sons is listed in the bible as well.
My Joel Brown had 9 children, but only three lived past infancy, two sons named Henry and Robert and a daughter named Eliza. In 1816, Joel Brown and his family moved from Petersburg, VA to Raleigh, NC. The decendants of his son Henry stayed in Raleigh. The decendants of his son Robert (my line) lived in Wake, Chatham, Moore, Lee, and Durham Counties in NC. His daughter Eliza moved to Maury County, TN and most of her decendants are in that area. Joel's three children are easy to establish in NC and TN records.
I was seeking proof that Lockey was Joel's sister or that in the least there was some connection between them. I know Lockey was a Brown and I have an unreliable source that listed her as Joel's sister.
