I have a bunch of Czyzewski relatives who were largely in the Newark, New Jersey area from around 1900-1950. The start of the clan seems to have been Roman Czyzewski (1855-1930). I think there were then at least 3 kids, Anthony (1880-193x) who married Pauline Bielut (1883-?), my great-grandmother Barbara (1892-1932) who married Joseph Twarowski (1887-1957), and Unknown who married Mary Unknown. Some of them ran a milk delivery business.
I have a picture of Pauline and my great-grandmother together and various records, but my mom does not remember any of them, even though they just lived a street over.
