This is a 4 page, hand written letter dated 6 September 1975 (interrupted and supplemented on "August 7, 1975" but she must have meant September and September 8) from Lurline W. Hungerford to Stanley W. Hungerford.
The letter mentions the following individuals: Howard (Lurline's son born 1922), Michael (oldest son of Howard), Philip (youngest son of Howard), Jeanne (daughter born April 10, 1918 who has her own unnamed daughter and two sons), "Howard and his wife Freida," Freida's (unnamed) father ("85 years old"), Cleo (Cleo S. (Hungerford) Brooks; reference US2714a in the Surnames database).
The letter also contains a lot of biographical material about the people who she mentions.
Received 5 October 2015 from a family tree owner on Ancestry.com: Lurline was previously married to a man named Pierre Gaillard Sanders. With him, she had my grandmother, Annie Jean Sanders, so I am not related to George, just Lurline. George was my grandmother's step-father.
Received 6 October 2015 from the owner of that family tree: I knew her and her bird. The bird would yell out “Shut the damn door!” We called her “Little Grandma." She passed away when I was about 8 years old. Natalie.
