According to the 1883 Wash. Ter. Census,
Columbia Co. William and wife and two kids. JB, f, age 3 and LG, m, 1.
Later census shows wife's name as Ethel M. b. oregon 1865
and daughter's name as
Belle.
Western marriage records show William H. Wilson married Ethelyn M. Brown 17 Oct 1878,
Columbia Co., WA.
Guy and Ella had two daughters, Maybelle b. 1905 and Kathryn b. 25 Mar. 1914.
Looks like Guy died in Spokane on 1 Oct 1948.
Wm's wife may have died before 1920 as Wm is living with Guy and single. Haven't found William in 1910 or 1900 census. Hopes this helps.
