I really hope you are still around to get this. I have a Nikola from Chicago I have been researching and I am interested in his Croatian line! It is actually my husbands family that is related and they spell it Hecimovich, so slightly different. Do you know anything about Nikola's parents, wife, birthday, etc? Here is my information:
Nikola was born Dec. 6 1885 in Croatia and immigrated to Chicago April 1, 1913. He died Jan. 7, 1956. His wife was Ika Potnar and she was born Jan. 12 1886 in Croatia and immigrated to Chicago May 23, 1913. She died Jan. 30, 1972. They had 10 children, all born in Chicago. Nikola and Ika are my husband's great grandparents.
