Looking for Farrells and Daltons of Australia

Looking for descendants of John Dalton who married Mary Ann Farrell in Tasmania in 1849. They moved to Bendigo
Victoria in the early 1850s. John died sometime in the mid 1860s and Mary Ann remarried a Francesco Morandi.
Their daughter Mary Ann married a Mortimer Quin who died and she remarried an Alfred Kingsley who was the father of my mother Gladys.
