My great-great grandfather, Thomas Pratt Washington (1806-1873), brought 50 to 60 slaves with him when he moved from Alabama to Texas in 1845. At the close of the Civil War, he owned 106. I've got a listing of over 50 of them by name, with most having the surnames they assumed after freedom. Their wives/husbands/children are noted in some cases, too.
This might be helpful for some and I'd be happy to share the list.
