Gertrude Monsen

Both her parents were English according to the 1910 census (but in the 1930 census her mother is listed as German) and her younger brother and sister were living with them in 1910 as well

In the 1930 census she is living with her father Charles in Bronx, NY

In the 1940 census she lived with her daughter Vera Kerrigan and her husband at 1324 Ogden Ave in the Bronx and she worked as a clerical worker for Housing and Building. Her name is listed in the index as Lally Gertrude but in the record it looks like Sally Gertrude to me (she was known as Sally so maybe they forgot her lastname?)
