Kells Parish Church and Graveyard 4
Kells Church & Graveyard 
Extract from ch. 13, p. 140:
Old Galloway, by Ian L. Donachie and Innes MacLeod
... stone erected by Capt. John Gordon in memory of his gamekeeper, John Murray who died in 1777 after 46 years service, showing his gun, powder-flask and fishing rod, and a gamebird, and on the reverse a suitable and perfectly cut verse by Mr Gillespie the parish minister:
Ah, John, what changes since I saw thee last;
Thy fishing and thy shooting days are past,
Bagpipes and hautboys thou canst sound no more;
Thy nods, grimaces, winks and pranks are o'er.
Thy harmless, queerish, incoherent talk,
Thy wild vivacity, and trudging walk
Will soon be quite forgot.  Thy joys on earth --
A snuff, a glass, riddles and noisy mirth --
Are vanished all.  Yet blest, I hope, thou art,
For in thy station, weel thou play'dst thy part. 
As can be seen from the photographs below the stone has suffered the ravages of time and the inscription can no longer be easily read.  The detail of the carving is still quite distinct.
black/white  photo, below right,
is from the above mentioned book:

Head of this stone shows two seated figures blowing trumpets announcing the Day of Resurrection.

This fragment shows the top of a tree with a bird.
Stone above depicts Adam and Eve standing either side of the Tree of Knowledge in the Garden of Eden. A serpent representing the Tempter is entwined around the tree.
Donnachie and MacLeod, referring to the above, state that there are three such Adam and Eve stones in Kells.  This one, now removed from its socket is leaning against an enclosure.
The writer found fragments of another stone, see photos left and below, the  third stone could not be clearly identified. The previous page, second row left, may be the third stone but it has no Adam and Eve theme, only the tree symbol.
