Hello Sue,
A very big thank you for that information, all I need now is to find when their son Thomas Hitchcox born c1841 and emigrated to Australia. I can't find him any where on the shipping records. The only information I could find is he married Mary Whitmore in Yass, NSW in 1877.
I am so grateful for your help, I am sorry I cannot find any more information about him here.
