Murphy Cronin Crowley Families

Sorry, I forgot to include his father's name!

I am searching for my Great Grandfather's parish and family. His name is Denis Murphy and he came to Australia, Victoria somewhere around 1860. He married Ellen Brockinshaw in Inglewood, Victoria in 1885. On his marriage certificate he gave his father's name as Denis, his mother's name as Anne Cronin, his age as 40 and his birthplace as Blarney. His birthplace on the marriage certificate is not clear but it looks like Blarney and the county is definitely Cork. He died ten years later in 1895. On his death certificate his age is given as 60, his father's name as Denis and his mother's name as Anne Crowley. Any suggestions as to how I might trace him?
