While Ira Lloyd Sloan is living at home in 1920 with his parents in Olney, and Dorothy's family (parents and 2 sisters) is there also, Dorothy Barbee appears in neither home. I remember Nana telling me that she was first married when she was around 14 or 15 because she had been invited to see a baseball game elsewhere and her parents wouldn't let her ride the train with a male to whom she wasn't married. The marriage was short-lived. Sometime after the 1920 census she married Ira Lloyd Sloan, and Mary Wanda (Nana) was born in 1921 in Olney.

There is a Dot Richardson living in the Kennedy house in Olney, TX in 1920. Could this be our Dorothy Barbee?
