My great grandmothers maiden name was stelmach. Her name was Mary (stelmach) swieca. They lived in dunkirk/fredonia ny. As far as I know her father's name was Albert stelmach, her mother was rozalia biz, her paternal grandparents were antoni stelmach, and katherine pienta, and her maternal grandparents were Michael biz and francizska Portka. Mary had five children and died in chautauqua county. Wondering if there is any relation ?
