My Kaczynski family is from the Chicago area.
My GrGrandfather, Peter B: Feb. 21, 1843 in Poznan. He married 1st Anna Warszewski, 2nd Madislava Zdrojewski. He had 2 brothers Paul and Jan and 2 sisters Agnes (M: Glasowa) and Susanna (M: Kaczmarek). I am not sure where in Poznan they originated from. I am also curious about the genealogy of Ted Kaczynski.
