Thanks for your message, but it's bad news on the churchyard, though! As far as I know it was always surrounded by a white sandstone wall about 7 feet high. There are steel railings on the farthest side from the road, but they were built in the 70's when the original wall collapsed. There is also a small stone watch house
(against grave robbers) made of the same material as the walls, so they have been there a while! The church itself was closed and demolished in the 1930's, (a new, bigger building being built across the road) and the churchyard was more or less left to get on with it.
Now, to Logan's grave. I am looking at a photo of it as I write (taken about 5 years ago) and it is a ground marker being about 6 feet long, and is about 2-3 feet high, in a 'hogback' style. (That is, curved sides coming to a slight ridge running the length of the stone.) I can't remember what kind of stone it is, but it's grey, and pretty solid. The inscription, running from east to west on the northern side is as you say, except for Grandma, who is named as Elizabeth Smith. There is also a corrected error on the stone, but I can't remember where. The other side of the stone has Elizabeth Smith's dates, but that's all.
Unfortunately, today, the stone is sinking into the ground and is covered in moss, with a lot of humus and other detritus helping the process along. However, there is a young tree (about 45 years old now) growing from under the stone which I always thought was rather nice.
As for the cemetery itself, It has been vandalised to the ground, and is now an eyesore. I am new to this computer thing, and can't yet do attachments, so I'll go just now, and continue on a new post. More to come!
