Success as Laird of Glenorchy
Grey Colin was a sprightly laird who used his aggressive and single-minded determination to transform a stagnating lordship into a power centre dominating the entire Breadalbane region.
In the judgement of the Glenorchy family history, The Black Book of Taymouth, Grey Colin's leadership re-established the house of Glenorchy (BBT 20-3).
It categorised his achievement:
- he produced a large family and was succeeded by an adult male heir
- he 'conquesit' (acquired) many lands
- he built or enlarged several castles
- he was 'ane great justiciar'
