Sir John de Grahame’s Castle, also known as Dundaff Castle, belonged to the Graham family in the 13th century.

In 1370 Sir David Grahame of Dundaff resigned his lands of Lynton Schelis in the Carnmore on the estate of Lyntounerothiryk due to purprision (encroachment on another’s land). However any dispute seems to have been an amicable one as Grahame was then granted the same lands by Sir James Douglas of Dalkeith who owned Lyntounerothiryk.

Sir James’s uncle, Sir William Douglas of Kincavil, Lord of Hermiston, was married to Margaret or Marjory, daughter of Sir John de Grahame of Dalkeith, Abercorn and Eskdale.
