Thanks for that info nannyj, I'll have to have a think about the Joseph Harris who died in 1871, his age of 56 would see him born about 1815, unless of course whoever supplied his age made a guess and underestimated it. At least I've only to check marriages for him, by the way hope you don't mind me asking but at what year did you start the burial search?
Had a look at the online Coggeshall Congregational baptism registers yesterday, thanks to Smudwhisk's post, no Joseph Harris but was able to gain data regarding one of my Norfolk/Essex Dalton associated families, the Anthony family.
