Hi folks, I have a census listing for 617 Humboldt Street, in Brooklyn, NY in the year 1900 for Mathilda STAMPF age 62 and still living with her were her sons August, age 32; Frank, age 29; Edward, age 27 and her daughter Rosie (also seen as Rosa elsewhere), age 24. The men's occupations were "day laborers". Would anyone have these STAMPFS...possibly sometimes known as STUMPF....in their trees? Maybe looking at them as Stumpf would unravel something...but they, so far have clearly been listed as STAMPF everywhere. Joanie
