Hi, I went to Kirkmichael Church/sunday school many moons ago!
The church yard /headstones were very worn then and we were told at Kirkm/primary school it was a v old burial place with one corner devoid of headstones as this was where those who perished in the 'black plague' were interred. The ministers daughter, i think her name was Sheila Tosh, made up a booklet of the headstones and the inscriptions but I would doubt if it still exists: if it does, it would probably have gone into a library somewhere.
