In the 1930s, my father and uncle both reported on their SSA-5 application that they lived at 21 W. Bates St., Sans Souci, Greenville Co. I would like to determine if that address might have been a "single-family" home or a boarding house. Both men worked in the construction industry which often meant moving around constantly. Can anyone help me or direct me to a source for that kind of information? Any help will be appreciated.
