My maternal great-grandparents immigrated from Hungary around 1907. Their names were Michael Zuzchik and Vilma Sipos Zuzchik. On a passenger manifest for Vilma, her father is listed as Vincenze Sipos and it looks like he lived in Senica (now in Slovakia). Her death certificate lists her mother as Katie Gravda (originally from Austria-Hungary). I don't know hwo Michael Zuzchik's parents were. I know the borders in Central Europe changed constantly but where do I go from here?
