Looking for George Pitcher and Sarah Pitcher Cooke

George Pitcher and his wife Sarah came to Australia in 1853 aboard the shiop "Circassia" they had their children with them Sarah Jane aged 10years, Clara Isabella, my G.G. grandmother, 8 years, Fanny E.
aged 6 years, George Thomas 5 years, and Charles 1 year, they lived in the Collingwood and Fitzroy suburbs in Melbourne. Hoping some one has a connection to them.
