the Nicholas Middleton who married Catherine Bradly in Woolwich 19 Dec 1843 gave his father's details as Nicholas Middleton, shipwright. The father of your Nicholas is John, isn't he?
The parish entry for the 1837 marriage shows that Nicholas to be of the Royal Marines.
So something is awry.
We have seen and noted this fact. We have searched for a Nicholas Middleton, born c 1814, Torquay, mother Sarah Earle, father Nicholas but cannot find one.
We have found
Nicholas Wadlin Middleton born 1813 December 29, Tormoham, Torquay, Devon, England
Baptised, 30 Jan 1814, Cockington, Torquay, Newton Abbot, Devon
Parents, John and Sarah Middleton.
A John Middleton, marries a Sarah Earle, 1813 August 5, Cockington, Torquay, Newton Abbot,

Nicholas cites his Mother as Sarah Earle, to receive his money on his RN Alllotment papers.
This changes to his wife, ELIZA, in 1843.
