Photograph of a young man identified on reverse as Charles Coy, brother of Leona Richards. The photograph was taken by the Spurling studio of Dover, Maine.
From online research, hopefully correct:
Charles M. Coy was born 22 June 1893 at Monson, Maine, the son of Forrest H. Coy and wife Martha "Mattie" Bennett (Drake) Coy. His paternal grandparents were Charles Melvin Coy and Elmira S. (Bean) Coy. His maternal grandparents were Elhanan Gay Drake and Delana Snow (Strout) Drake.
Marion was a teacher in Dexter, Maine, as I've heard from a reader, one of her former students.
