James I have had a look at my tree and I have the fillowing Thomas's listed but none seam to come close. By the census this Thomas would have been born in 1818 in Maidstone.
I have these...
Thomas Hedges 1801 b Unknown Married Eden Brewer
Thomas Hedges 1826 b Unknown Married Unknown son of Thomas and Eden
Thomas Hedges 9 March 1853 b Panfield Bocking Essex Married Unknown, son of James and Eliza
Thomas Hedges 1907 b Dartford area Married Elizabeth Loveridge son of Samson and Eliza Julia
Thomas Hedges 1868 b Chatham Married Unknown Son of Alfred and Eliza
I can provide more detailed information if needed but based on his age given he doesn't look like one of these.
As you can see I have very few marriage details for any of my Thomas Hedges. I would imagine he fits in my family somewhere but where I couldn't begin to guess.
Need more on him before I can place him somewhere.

Added Sorry missed this one I have
Thomas Hedges 1876 b Sittingbourne Married Unknown Son of Elias and Alice.
