Your request caused me to look at my Burials Index and I found no listings for Tate at Lonan.
Hmmmmm.
Investigation shows that the microfiche supplied by the FHS has several pages missing from it so there will be some corrections forthcoming.

The only Godfrey was buried 30 Nov 1857 aged 28.

There is an MI that could be the one you want:
