I ma researching the Krystyniak family from Plock, Poland. Rozalia (nee Arminksi) and Marcin Krystiniak had nine children, five of whom immigrated to the US. One daughter (Florentyna) married in the US, had 2 children, 1 of whom died, and returned to Poland for reasons unknown. The father Marcin Krystiniak is seen on a census living in Buffalo, NY. It is believed that Rozalia died in Poland.
Three daughters, Zofia, Bronislawa (Bernice), and Kazimira moved to and stayed in the US. Zofia in Philadelphia and the other 2 in Detroit. Thier brother Stanislaw also moved to Detroit and resided there until his death.
They had a younger brother Wiktoryn who fought and died in the Battle of Konary in 1915.
I would like to find out more information about the other siblings that stayed behind: Zygmunt (1890-?), Kazimierz (1894-1939, and Regina (1898-1943), and Maryanna (1889-?).
Any insight you can provide would be greatly appreciated!
