Looking on the Unassisted Passenger Lists on PROV website there is a George Redman adult, Alfred and George Jnr children, arrived on the Ben Nevis in January 1853. This could be George snr and the two elder sons, who came out first with the rest following later.
Charlotte 35, Edwin Josh 7, Frances 7, Arthur Stephen 5, and Laura Ellen 3, were on the Mermaid which arrived May 1835.
You can see these passenger lists on film at PROV in Melbourne.
