My husband's grandfather came from Stari Grad in 1908. His name was John Berkovic (born 1903) and he traveled with his mother, Kate Berkovic who listed:

Former Residence Starigrad next of kin father Nicola BOGDANOVIC.

She arrived with son Ivan age 5 and mother in law Klara age 60 (widow)(senile) and Jela BOGDANOVIC age 20
Destination to husband Jacob BERKOVICH at 116 W?? St Fresno CA Klara also listed her son Jacob at this destination. Jela was going to Betrothed KOVACEVIC, John at 424 North St Fresno, California.

Kate and John Berkovich had 6 more children in California.

Can anyone advise me how to find church records for John's birth on 4 Jan 1903, or Kate and Jacob's marriage?

Thanks!
