Bruce, In Archaeological and historical collections relating to Ayrshire and Galloway, http://archive.org/stream/cu31924092901606#page/n145/mode/2up, Vol. V, pp.82,83, it relates that an old man in Sir William Maxwell’s service was cleaning out a channel. This appears to be the crannog in the White Loch of Myrton. The Black Loch of Myrton is also mentioned in note 2. Wonder of the McCulloch descendants may have more information as they may have sold the property to the Maxwell family. Regards, Shirley
