I am researching the Liebentritt and Gergitz (Czerkits) families for my son-in-law, James Murray.
I have found the name Ignatz as a brother of Johann Liebentritt in Johann's passenger list entry. The family already knew of the brother named George, who preceded Johann to Chicago. Ignatz was the relative that Johann last lived with before he left for the US. Other possible brothers seem to be Franz, Franciscus, and Aloisius. Parents are Franz Francisus Liebentritt Sr. and Maria Frei or Frey. I have no information on the Frey family. Any information you have would be greatly appreciated.
