I have been tracing a line of O'Callaghan's in Australia.
When I went to the grave of one of the original O'Callaghan's of my line in Victoria Australia, it noted that he was born at Dromaneen Castle on his tombstone. He was born abt 1836 so I figure this cannot be so, however I still feel he must of had a connection there before he came to Australia with his wife in 1874.
I was lucky enough to visit the castle in 2012, and met some wonderful people in Mallow but still have not found any direct connection.
His name is JEREMIAH O'CALLAGHAN. HIs death certificate says his father is THOMAS O'CALLAGHAN and mother MARGARET GEARY. He was married to ELLEN TURNER in Glantane in 1873.
If anyone has found anything with these names I would love to hear from you.
