I posted this on the Massengale query you had. I hope it helps. On the 1850 Hot Spring County, Hot Springs, Arkansas Charles Magby b. 1842-1843 in Alabama is listed. He is the son of David Magby b 1795 and wife Betsy.There were at least 2 brothers (David and Robert) and at least 5, what I presume to be nephews, of those men who all came to Arkansas at the same time from Alabama. Those 5 brothers may be the children of William, but there is no record of him in Arkansas by the 1850 census. Perhaps he died here before the census.
