I am seeking information about my great-grandfather, Wojciech Wolek (perhaps Walek) who lived in the Galicia region of Austrian-ruled Poland. His wife's name was Jadwiga. His children's names were Jan (born 1883), Sophia (born 1888 in Ropczyce), Jozef (born 1894) and Marya (born 1902). All four children emigrated to the United States and lived in Philadelphia, Pennsylvania.
