|The original lands
of the family of Colquhoun were along rhe river Clyde at the village of
Kilpatrick. This was where Unfridus de Kilpatrick had his holding
when granted the lands of Colquhoun. On the banks of the river stood
the castle of Dunglass. There is very little of the original castle
remaining now, just some baseline stones along the wall that remains from
later buildings. The castle was about three miles south-east of the
much more imposing castle of Dumbarton.
It is said that the
castle was built in about 1380, and was certainly used as a residence by
Sir. John Colquhoun, Chamberlain of Scotland, during the period from 1439-1478.
The castle was not as formidable as Dumbarton Castle, but it's position
commanded the movement of shipping on the river Clyde and was therefore
of military significance.
