I am presently researching the following surnames:
CZECH, CABKA, FOLTA, HRYCAJY, HRYCOY, MUZYKA, LACHO, LICHOW, LECHOW, LECHIW, LEMECHA, LEMECKA, LITVIN, LITWIN, LYTWYN, SAWKA, and ZIMAK.
These families entered Canada from the Galacian /Austrian regions in the early 1900's. Many originated from the Parchacz/Sokal, Turi/Brody and Pozdymir/Sokal areas.
