In the 1910 Cenus of Conover Street Brooklyn, Kings County, NY, we find this family:
Peter F. McCarron 35 m1 10 NY NY NYmachinist Theresa M. 30 m1 10 5,5, NY Germany Germany Peter 9 NY NY NY Ernest 7 “ Elizabeth 5 “ Margaret 4 “ Theresa 2 “
Theresa M. McCarron is Theresa Mary Prinz born about 1880 in NY. After this census and before the 1920 census, Peter died and she married John Hogan. In the 1920 census, John, Theresa and her original children were at the same address in Brooklyn, except in this census, it is stated that her father was born in Germany and her mother was born in France. We think her mother's given name was Ann, Anna, or Annie. I've tried to find her parents in census data, but so far nothing. Any help would be appreciated.
