Notes for Mary Dehart
Some online family trees show her parents as Allen Dehart and Susan Cline (or Susan Conn), but I do not know the source of that attribution. Allen and Susan were both living in 1900, and it seems more likely that at least one of her parents was deceased by then, since it is uncommon to send a child as young as 9 out to live with another family if both parents are living and not separated.

The Ohio deaths database lists Mary Willis, age 75, died 15 July 1966 at home in London, Madison Co., Ohio, widowed.

The SSDI lists Mary Willis, born 5 Aug 1890, died 15 July 1966, last residence London, Madison Co., Ohio.
