Hi....the children seem pretty straightforward in the census'. In both the 1910 and the 1920 census John H and Delia are living in Hailey, Idaho with three children: Maude D, John W, and Harold R. Then in 1930 Delia is a widow living in Los Angeles with her son who is now calling himself Robert H (Harold R). She is managing a rooming house and there are several unrelated lodgers living there.
Delia dies in Los Angeles on September 22, 1964. Her mother's maiden name was Huntsman.
