Hi Dee-Jay
Thanks for all your help

and encouragement. Just waking up, Sunday morning 8:00am in Brisbane, Australia.
Just a correction to start - I put the wrong age on Thomas at his arrival in Australia,

it was 28 not 32, which would give him DOB of 1824 or 1823.
Marriage Certificate: Charles and Mary. I bought a registered copy from GRO, hand written copy.
Application No. COL361191, 4th Sept 1851 at the Independent Chapel in the Parish of Andover, Southampton.
Charles Paice, 33, Bachelor, Auctioneer, Winchester St, Basingstoke. Father: William Paice - Upholsterer.
Elizabeth Mary Hayes, 20, Spinster, no rank/profession, High St, Andover. Father: Edward Hayes - Draper.
Witnesses: Edward Hayes, William ?anner (can't read first letter, could be V) Mary Ann Paice, H.Paice, C.H.Paice
I went through the 1851 census and couldn't find a Thomas that would fit, I will check again.
Again, thanks for the help, looking more positive.
