William Conley 1812 1858

I'm looking for help researching William Conley (1812 -1858). He was born in Dublin Ireland and came to Aust as a convict. He married a Sarah Taylor and had a daughter Matilda Conley 1846 Albury Vic. She died 1942 Camberfield. She married my great great great grandfather John Watt 1841-1933 from Scotland. I can't seem to locate William Conley's family history. Can anyone help?
Thanks
Michelle
