No, Frank Rzepinski would have to be a cousin of my grandmother, Antonina (Antoinette, nee Rzepinski) Wozniczka. Her siblings were Marianna, Martin (renamed Rzepinski), Jacob (or Joseph, deceased in early life), and Julianna. Their parents were Anton and Josephina (nee Lemanczyk). Anton's parents were Jacob Christopher and Marianna (nee Kosobudzki, or Mariciem Kossobudcki). Jacob's parents were Adalbert and Hedwig (nee Gierszewski, both born before 1800).
