Not that this helps one jot in answering your dilemma, but I spent some time today with the Coton clan.
When William Coton married Elizabeth Deacon in 1828 one witness was Ann Deacon the other Malby Coton.
Luckily Malby lives through 4 census and dies 1874 (he is easy to find). He gives his pob as Grantham Lincs
There is a bap for Malby s/o Ambrose and Mary 19/4/1803.
Malby is a cabinet maker
I then looked to see if I could find a brother William for Malby
No William bap in Grantham but
A William Coton was bap in Stamford Lincs 9/12/1799 s/o Ambrose and Ann

William Coton married Sarah Duel 19/3/1820 at Leicester all Saints they then baptise 3 children there
William 29/9/1820
Mary Ann 18/11/1824
Sarah 31/8/1826 - buried 1827
William is listed as a cabinet maker
Sarah Corton(sic) is buried 24/6/1828 age 28 - her address Sanv[o]y Gate matches the baps of the 2 girls
This leaves William free to mary Elizabeth Deacon on 1/9/1828 - just a couple of months later
After all of this I am no closer to finding a death/burial for William Coton 1828-31 (or later if he was still alive in 1831)
