Hi Goldie  can’t find any headstones for John & Janet, George & Margaret
in index
From the dates of burial they would be in Old Falkland cemetery
but there is no listing of a stone for them in Stuart Farrell MIs
for  Falkland old cemetery publication no 16 FFHS.
I have no Sutties  in my index for Falkland
But 
www.Scottish Monumental Inscriptions has Sutties & Grants
Listed in their index cost £6.50 + post
Do you know who the children married?
I do have other Suttie stones but need 2 names to check index
eg George  Suttie   Margaret Arthur
