Dillie's first husband Edward Monroe died 03 Apr 1913. Before 1920 (US Census) she had married Bill Schertz, and was separated from him and living with her sister Carrie and Carrie's husband Andrew Zaich, at Los Angeles:

SCHERTZ, DILLIE M (1920 U.S. Census)
CALIFORNIA , LOS ANGELES, LOS ANGELES
Age: 35, Female, Race: WHITE, Born: WI
Series: T625 Roll: 110 Page: 48

Note that this census record confirms the spelling of Dillie's second husband's surname SCHERTZ.

The census image includes designation “Married.” I don’t know a date of divorce.

George Zaich was also living at the same house. Other data indicates George and Dillie were married later in 1920. Maybe they were waiting for her divorce from Bill Schertz to become final.
