In the 1910 Census, Eva S. Wallace is living in Hagar Township, Berrien County. She is listed as 42 years old, a widow, was married for 16 years, had 4 children of which 3 were still living, was born in Kansas, father was born in Michigan, mother was born in Indiana. Her occupation was listed as hotel keeper which was then crossed out and "none" was listed. Living with her was her son, Phineas T. Wallace, age 15, born in Iowa, father born in Wisconsin and mother (Eva) born in Kansas.
In the 1920 census, Phineas is found in Chicago, (ward 28 of the city), married to Nora, age 30, and they had a son, Phineas, age 2 years and 2 months, born in Illinois.
I think this is the death info for Phineas T. Wallace, the son of Eva:
