If you're still interested in Mary Dearborn she was my Great-aunt. She was born 29 Sept 1898 and died in Mechanic Falls, Maine at the age of 57 on 06 December 1950. She is buried with her husband Coralus at Maple Grove Cemetry in Mechanic Falls.
I have obituaries for her and her husband as well as the following four children and some of their spouses:
Arthur Benson and his wife Ada Pearl (obits for both)
Virgil Benson and his wife Brenda Fifield (obit for him, death notice for her)
Prudence Benson and her husband Frank W. Kilbreth (obit for her, nothing for him)
Stephen C Benson and his wife Barbara Lane (obit for him nothing for her)
