This is not my Tompkins family, but I did check some census information:
Daniel Tompkins, age 46, born PA, RR engineer
Arvilla, age 39, born PA
George D., age 19, born PA, brush maker
Fredrick, age 12, born Illinois
Debra T., age 65, mother, born PA
George Tompkins, age 55, born PA, bridge builder
Deborah, age 54, born PA
D. D., age 34, engineer RR, born NY
Arvitta, age 30, born PA
George, age 9, born PA
Fred, age 3, born Ill
The 1900 census says that Daniel was born July 1835 in NY, that he was a special policeman, and that Arvilla was born Feb 1840 in PA.Arvilla was still living (alone) in the census of 1930 in her own home as a 90-year-old widow.
In the 1920 census (Chicago) in the household of Fred and Anna (both age 52) were:
Daniel D., age 32
John J., age 29, engineer
Katharyn, age 28
George, age 7
Dorothea, age 1 2/12
Fred was listed as a teamster, born Illinois; Anna born Illinois, her father b. northern Ireland, mother Scotland.
They also had several lodgers in the home and Anna was listed as a "landlady."
