My Grandmother's (Florence Zientek Mager) sister, Catherine Zientek was married to Frank Wirkus b 1893. Frank was the son of Frank Wirkus b 1868 & Elizabeth Mager. Frank Sr was the brother of Maryanna Wirkus Pestka. Actually connected thru the Mager side also. Elizabeth Mager Wirkus was the sister of my gr-grandfather, Vincent Mager. I'm thinking you must be the daughter of one the Schalk brothers?
