Patrick Collins, my ggggrandfather, was a member of the Royal Irish Constabulary. He was born in Co Limerick but as was the custom was stationed far from home and family in Co Down. After his seven years was up he married Mary Gribben.
Mary Gribben was born in Co Down her parents were Mary Carlin and John Gribben. They all emigrated to Australia from Liverpool in 1857.
John Gribben was born in Dromara Co Down about 1793. One of his sons Hugh emigrated to New Zealand and died there in Greymouth. There is a branch of the Gribben family in New Zealand today.
