Thank you. Your kind help saved me a 200 mile drive to and from the Clayton Library in Houston to merely find out that Scalf knew less about the Stepps in McMinn County in 1830 than I do.
I read the William Stepp household as likely a 50-59 year old couple with either eight children or five children, a son-in-law or daughter-in-law, and two grandchildren living with them. David Stepp is listed next to William and was almost certainly his son. McMinn County court records for December 1827 mention a James Stepp who was naughty enough to be given nine lashes at the public whipping post and I have assumed that he was the 20-29 year old male in William's household.
