Carsten, Could Hubatsch also be known as Hubtaschka.
My GrGreatgrandmother was Julia Hubatschka, born March 6, 1856 in Austria, her parents were Albert Hubatschka & Johanna Peltz or Beltz. She was married in Austria to Anton Mueller. She had siblings: Franz, born 1868; Johann or Joseph; Hondre and Maria. I have a picture of Maria that was taken in Wien, Austria/German. Also I just recieved some old German documents form a distant relative for Franz Hubatschka, they look like Birth/Baptism, Homeland, and Testimony Certificates all in German which I will need to get Translated into English. Julia and Franz emigrated to New Jersey, USA
