Hello! I am trying to trace my Great Grandfather's family. His name was Rudolf Perz and it is said that he was born in Triest, Austria (when it was still Austria) on 23 March 1883. He immigrated to the US in 1899. Very little is known. He had a brother Eugen Baldasar Perz born 13 Dec 1884 also in Triest. I'm not sure if they were half siblings or what. I have his naturalization certificate from here in the US as well as his passport, he last lived in Schalkendorf, Gottschee Krain. Was said to be German but naturalization went through as Italian because Triest was already a part of Italy at the time he was naturalized. Super lost, any help is GREATLY appreciated!!
He lived in Chicago in the US.
