Hi Vivien
Firstly, he would probably have married in
East Wickham (a parish in the Dartford registration district)
http://www.ukbmd.org.uk/genuki/REG/districts/dartford.htmlWho were the marriage witnesses? What was his father's occupation on the marriage certificate?
As his residence is given as Cambridge at the time of marriage, I would suggest that he was probably stationed at Cambridge and, perhaps, returning home to Kent to marry

I notice, from one of your other posts, that you have some possible birth places etc. for some of his children. Although not always, birth certificates and baptism entries do sometimes give the regiment of the father or at lease put the family in a given position at a precise date. Baptisms may be the "cheaper" option if the originals can be located.
http://www.rootschat.com/forum/index.php/topic,220260.0.htmlDid daughter Madeline marry Walter IMPLETON September quarter 1876 Islington registration district ref. 1b 393 and could it be her (with perhaps sister Alice) in the 1881 census at 40 Hampden Road, Islington in the 1881 census ref. RG11/247 folio 79 page 40?
Do you think he is part of the following family (children baptised to Benjamin & Elizabeth JURY)?
Josh Henry 3 Jan 1819 Wesleyan Chapel, Sheerness
Benjamin John 1 Jul 1821 Wesleyan Chapel, Sheerness
Edward Christopher 4 May 1823 Wesleyan Chapel, Sheerness
and, possibly
Josiah 30 Jun 1833 Independant Chapel, Chatham
