    Addition information: Great-grandfather Peter Karolowski was the son of Paul Karolowski (1893) and Jennie Olschewska (1889). Paul was born in Poland and was ethnically Polish. Jennie was born in either Poland or Russia.
    Elizabeth Monaghan was the daughter of James Francis Monaghan (1874) and Elizabeth Mary Weyant (1887). both from Manhattan. Elizabeth’s parents were Smith Thomas Weyant and Marie Anna Power. Elizabeth Monaghan I believe is of English along with Irish ancestry.
