shamrock on Family Tree Circles

My great-grandmother is Bridget Coll from Fedamore in Co Limerick. Her sister, Maria Coll, married John Clancy on 12th April 1875 in Fedamore, Co Limerick and they had 4 children in Ireland, Joseph, Thomas, William and Bridget. It is thought that after Bridget was born (1883) they emigrated to Australia. I would love to know more about their lives in Australia and maybe connect with any descendants of Maria Coll. I know her father's name was Thomas Coll and John Clancy's parents were William Clancy and Bridget McCarthy.
