Argyllshire / Re: Drysdales on Islay

That is interesting. I only have a John Duncan, child of Romeo Drysdale, b. 1810, on my tree, so I wonder, too, if this is the same person - I couldn't find any records as an adult for John Duncan.
By the way, I found this mention of Romeo Drysdale recently in an old textbook:

"Several portions of the rock are strongly magnetic, and affect the needle of a compass, brought near it, very considerably, causing it to vary much from its true pole. This circumstance is noticed by the historian Buchanan.1 “In the upper part of the Castle,” he observes, “is a piece of rock of the nature of a loadstone, but so closely connected and fastened to the main rock, that no manner of joining appears.” Professor Anderson, of the University of Glasgow, made repeated experiments on the magnetism of the rock, and the direction of its poles. On the south side, and near the top of the western rock, a large bare crag was pointed out to us, by Mr. Romeo Drysdale, the master gunner of the Castle, who has made various experiments upon it, and found it to be highly magnetic. This, from its situation, is in all probability, the rock alluded to by Buchanan. Mr. Drysdale says its influence has even been felt on the opposite shore of the Clyde."
