My great grand father was Ignatius Hursa, who I know little about.

B: 24 Jul 1881 in Croatia
Arrived in New York in 1906 from Rotterdam
Married in Philadelphia to Barbra Cicko
I believe he ended up dying in FL.

The problem is he came across alone, and I don't know where to being researching his parents.

I am familiar with the micro films, but I do not know any specifics about where in Croatia to even start looking.

Thanks in advance
