Born in Seattle, WA, William Ridenour seems to have had a somewhat unstable childhood, as his parents moved frequently, and divorced before 1940. They lived at 1756 Spokane Street in 1925 and 4325 8th Avenue NE a year later. (See Seattle, Washington, City Directory, 1925, p. 1187 and Seattle, Washington, City Directory, 1926, p. 1245.) The family resided at 3244 15th Avenue South in Seattle in 1927. (See Seattle, Washington, City Directory, 1927, p. 1347.)

The 1930 US Census indicated that William resided with his parents on Lake Road in Medina, WA, in rented accommodations that cost $35 per month.

Ten years later, he split time between his parents' two homes. The US Census of 1940 recorded him living with his mother and aunt, Margaret Leniger (born c. 1895 in KS), in an apartment building at 420 Terry Street in Seattle. (See, Source Citation Year: 1940; Census Place: Seattle, King, Washington; Roll: T627_4381; Page: 7A; Enumeration District: 40-234, accessed 09/13/2017.)
