Going back to original question:
Mr. Johnstone (probably of Lockerbie) held the lands associated with:
Poundland of Craig, Inifield, Outfield, Kelton, Conheath Riggs, Spittalfield, Netherwood, Nunholm, Dalscone, Auchencrieff, Burn, Searth, Dargavels, Wolfgills, Gladstonefield, Corsanfield and Cunninghams.
Every thing else was held by the Duke of Queensbury and the Marquis of Annadale with John Carruthers having Catherinefield (which may not have included the quarry and Tinwood Downs).
