I found the following information on Henry Byard and Josephine Flye:

This information is from: Obituaries, Humboldt County, 1911-1920, compiled by Marilyn Keach Milota.
Josephine A. Flye, died 20 Mar 1922 at her home, 1642 C Street, Eureka.Bur: Ocean View cemetery.Born 3 Jan 1840, Maine.Left son Willis Abbott & 1 sister.(Hum. Standard, obit 21 Mar & not. 22 Mar.)
THis information is from: Obituaries, Humboldt County, 1921-1927, compiled by Marilyn Keach Milota.
As shown with the obituaries, they aren't buried at the same cemeteries in Eureka.Also note that their address is listed as the same.She probably was a live-in housekeeper and inherited his house when he died.It also looks as if she was married more than once, as her son is listed as an Abbott.
