I'm researching the surnames of my maternal grandfather Edmund Tust aka Thust and of my maternal grandmother Amalia Julianna Hoppe. He was born in Zdunska Wola to Edward Tust aka Thust and Emilia Dresler, both of Zdunska Wola also. Edward Thust was born to Gotfried Thust and Anna Dorota Obst.
Edmund immigrated to the United States in 1913, his father and two brother's and one sister in 1922. The other siblings who were still alive stayed behind.
Edmund married in Allentown, Pennsylvania to Rosina Mulzet, where my mother and her siblings were born.
