Sir John of Inchmartin, who played a notable part in both phases of the war with England, was closely associated with Earl John of Atholl, and received from him a grant of Bonskeild and Borenich in Strath Tummel and Collie Bhrochain at the confluence of Tummel and Garry. He also held, by inheritance from his father, a considerable estate in upper Strathardle. One of his sons, also John of Inchmartin, appears in the early years of the fourteenth century as parson of Rannoch, a living with which he must have owed to the earl of Athollís favour. The Inchmartins were connected by marriage to another knightly family from the Carse of Gowrie, the Camerons, who were tenants-in-chief of the neighbouring fief of Baledgarno. Like the Inchmartins, the Camerons were also tenants of the earls of Atholl, and again like the Inchmartins the Camerons took their turn at serving as sheriffs of Perth.
