Not sure if you're still checking this, but my dad's family immigrated to Three Rivers from Galicia in the early 1900's. Please contact me if you need more information shellmarie08 at gmail . com.
Some surnames I have are Frydryk, Frederick, Trzeciak, Swiatlowski, Bercier, Baran, Czerwiec, Mistarka, Wojtowicz and Niedziela. They were a very close-knit family, living very close to each other (often next door neighbors) and many still live in the Three Rivers area.
