Marriages of Docking Norfolk

[Anjo]

Hi I am looking for the marriage details of a Robert Jennings born 1810 in Docking to a mary Melton also of Docking she died in 1886 at the age of 78 which would give her a birth year of 1810 ish. the census's confirm this. What I really want to know is who Mary's father was and if I could find her marriage entry maybe that would mention it.

On Ancestry I have seen the index card for the marriage as 1831 and a personal entry on the Lds site has the marriage date of 22 Apr 1831 can anyone find and send me the  details of this marriage or have any idea who or how I can find her parents??

The Jennings have married into the Meltons already so I would love to tie this loose end up as well. I would really appreciate any help on this.
All the best Anjo
