I'm looking for any siblings of Vladimir Mihajlovic, my grandfather, born in the region of Srem, Yugoslavia (Serbia) in 1908. He married Elisabeth Reidl in about 1937 and migrated to Australia in 1950. He was the eldest of about 14 brothers and sisters. His father was also Vladimir, and his mother was Katharina. I don't know her maiden name, but I think she died quite young.
If anyone has any info, let me know. I have heard a rumour that one of his brothers migrated to America.
