I am looking for any information on my great grandmother, Kostyna Maria Dzialo. She immigrated to the US with some of he siblings: Joseph, who settled in Philadelphia, Michal and Rozalia who settled in Chicago as did Kostyna. Kostyna gave birth to my grandfather on May 12, 1913. I am hoping to find clues so I can figure out who his father might have been. Also, I would like to know what part of Poland they might have come from.
Any help is appreciated.
