Alveretta Bennington (b. abt 1916) parents are Henry & Ottie Doty (Leota in the 1930 census). I think the Ruth Doty you're referring to is Annie Ruth Doty (b. Sept. 8, 1911 - she would be about 26 in your picture) m. Walter W. DeBolt in 1929. If she was called Ruth "Doty", then was she divorced or widowed? Her parents are John S. Doty and Minnie Virginia Ray. John S. & Ottie's parents are James Alexander Doty and Mary Ellen Pelly. Henry Bennington & John S. Doty are living next door to each other in the 1920 census in Moundsville.
Furthermore, Henry Bennington's parents are Martin Van Buren Bennington & Mary Doty. Mary Doty and James Alexander Doty's parents are Henry Doty & Rosannah Cutshall. Thus Henry Bennington & Ottie Doty were first cousins.
