Using FamilyAearch, there are 2 other Burnham marriages in Orton Longueville
Joseph Burnham & Elizabeth henson 7 Aug 1820
Christiana Burnham & Stephen Townsend 17 March 1828
The only parish entries for a Kezia in that parish are Kezia Burnham's marriage, Kezia Butterwick's baptism & marriage and a baptism 1 April 1809 for Kezia Bonnor, daughter of John & Jane.
Seaching for Christana, there's a baptism for Christy Bonnor 2 March 1806, daughter of John & Jane.
John Bonner married Jane Lambert 21 Oct 1805

It looks to me that the family started off as Bonnor but became Burnham.
