My grandfather, Jozef Mazur was married to Rose Lesny. They had 10 children: Joe, Edward, John, Mary, Stella, Sue, Nellie, Josephine,Helen, Sophie. Jozef's parents were Edward Mazur and Mary Pawlowski. Jozef had a brother, John, and a sister, Adele Costello, who both lived in Monessen. I think that John lived in the general vicinity of Forest Street, but I'm not sure. I know that John is buried in St. Hyacinth Cemetery, Monessen. Does any of this help with a connection?
