Hi. I don't know if you found any more info on the relative you are looking for since you posted this back in July but If you search for Artistotle Middleton you will find the 1930 census for him and his wife "Carrie" who was born in 1904 in SC. At that time they had 3 sons (John, Preston and Edward). There is also someone who has Aristotle Middleton and Carrie in their tree along with all of their children (there were quite a few). You should try contacting her.
