The National Burial Index gives the following information:
Mark Walton Buried at St Mary's, Brampton on 29 March 1830 Age: 56
Mary Walton Buried at St Mary's Brampton on 6 Sept 1833 Age: 53
Ann Walton Buried at Spaldwick St James (Huntingdonshire) on 28 Jan 1892 Age: 71
Couldn't find any of the others, although there are many more entries for Waltons in Brampton (and a few for Peace), which I'd be happy to look up for you.
I checked the 1881 Census and there were no Waltons living in Brampton by that date. There are lots of people with the Walton surname in other Huntingdonshire villages, particularly Needingworth, Eynesbury, St Neots, & Somersham. I did find Ann & Robert Peace were living at The Bull, Ch Hill, Brampton. Regards,
