I am 99% certain it is 11, rather than 14. It is quite normal to see the location of a grave being given in relation to fixed points in the kirkyard, here Buie's tomb and the west dyke (= wall) of the kirkyard.
Thornybauk in 1817 (follow the middle fold of the map down until you come to the first "proposed basin" coloured in blue - Thornybauk is just below that):
