Send a message to the person who requested a photo of the grave monument of Thomas Johnston with the following comment:
I belive that this is a family monument on my wife's side. If my research (and your photo) are correct, then Agnes Craig Johnston is a daughter of Thomas Johnston (who worked as a Wright in Edinburgh). Her brother (i think) was James Hope Johnston, who was killed by natives in 1843(?) whilst on board the 'Brigand' in the south seas near Australia. If you could send me a copy of this monument, then I may be able to connect to and prove my research of other family members that I have been researching for a number of years. Many Thanks Trefor Jones. (I visit Edinburgh occasionally and will gladly pass any photos of monuments I take to your excellent project.
