My mother, Flossie Ann Crowder, is in the back row. Looking at the picture, she is 2nd girl from the end.
She has on the back of this picture Sulphur, OK. I have 2 of her report cards when she was in High school there. They are dated 1916-1917 and 1917-1918. I don't know when she moved to Sulphur. Her mother, my grandmother (Matilda Elizabeth King) died 7/10/1917 and is buried in the IOOF cemetery at Norman or Moore.
