I'm researching a line of cousins on my Grandmothers side. A Rozalia Toczko (who's existence has been validated already) arrived in NYC on 28 Sep 1909 going to New Britain to her brother Dominik. I don't have any other records for her. Dominik Toczko has a 1920 and 1940 census. A wife Amilia and kids: John, Anne, Mary and Helen. A potential arrival for him has him going to a brother Jan in Middletown who I also cant find, unless I assume he changed his name to Joseph which would be odd.
There IS a Jozef Toczko with a wife Anastasia and kids, Stefan (1911-25) Eugeniusz, Josefa, and Leokadja. but they lived in RI and Brooklyn.
