WILLIAM FINN and ANN DWYER or DOYLE

My GG grandfather William Finn,was born in approx 1829 in Tipperary and married Ann Dwyer or Doyle in ?.possibly 1857. Marriage was witnessed by Catherine Connors. They had Martin Patrick Finn in 1858 in Tipperary, and Jeremiah Joseph Finn in 1862 in Nenagh Tipperary. Ann, Martin and Jeremiah came to Australia aboard the Sir Robert Sale in 1865. William does not appear on the passenger list and am unsure how or when he came to Australia, although have scoured all emigrating lists. William passed away 16 October 1910 in Sydney. Ann passed away 2 June 1912 in Sydney. From William death cert. it states his Father's name was Dennis or Denis and his Mother wasAlice Shanahan. Ann's parents according to her death cert. were James and Ellen Dwyer. If anyone has any information on this family in Tipperary I would appreciate it very much.
