Hello! My great-grandfather's name was Jacob Ivicisics and he was born in 1886 in the city of Weisskirchen aka Feherntemplom aka Bela Crkva, which was a part of Austria Hungary, then Yugoslavia, and now Serbia. Jacob's parents were Martin and Julie Ivicsics. I'm suspicious that the spelling of their surname was changed when the came to the United States in the early 1900's. Does anyone have any information about my family?
