Today I sourced the census record for Susannah (Pefley) Hoover in the 1920 census of Los Angeles County, CA. Susannah was living in the city of Pomona in the Maud LaRue household. She was listed as an 81 year old widow, mother of 2 children, with only 1 living.
As of yet, I do not know the relationship to Maud LaRue. Maud was aged 27, single, born in Kansas - her father born Kansas and mother born Indiana.
