Lou May Fullerton (20 Jan 1869 - 21 Jan 1953)
Lou Fullerton never married and lived at home until her parents died and then she moved in with her married sister Eva Fullerton Warriner. They continued to live together after Eva’s husband died.
She is listed in the US Census of 1900 as a photographer. In all other years, 1880, 1910, 1920 and 1930 her occupation is blank. Even her death certificate in 1953 shows her as a “retired” Music Teacher.
The US Census of 1910 and 1920, have her name as Lula M. Fullerton. In 1930 and 1940 it is Lou M. Fullerton.
From these scant records it appears that any photography by Lou Fullerton would probably be from around 1900.
