I've been researching my families Eastern European history since 1993 (from Shamokin/Coal Township/Mount Carmel areas). The surname in question is spelled Kowaleski in Poland (Americanized to other spellings). The two most well-known Kowaleski families in Shamokin were the baseball family (Antoni was the father, immigrant of Poland) and Dr. Kowaleski's family (Michael was the immigrant father, from Suwalki province in Poland). Both families, to my knowledge, were Polish, not LIthuanian. They are all buried in St. Stan's Polish Cemetery, not St. Mike's Lithuanian cemetery. Hope this helps.
