1930 census, the last one available, shows only one Loraine Downs in Louisville, Kentucky. Not sure if this is your but thought I'd pass it along.
1930 Louisville, Jefferson, Kentucky
Downs, Julius F., head, 26, 1st married at 21, Ky, Ky, Ky
Downs, Loraine, wife, 25, 1st married at 15, Ky, Ky, Ky
Downs, Edith, daughter, 10, Ky, Ky, Ky
*this must have been Loraine's 2nd marriage. Julius indicates that he was 1st married at 21 (5 years previous) and Loraine at 15 (10 years previous)
