Colquhoun Coat of Arms, Rosdhu

This evening, I am posting information on Clan Colquhoun which is based on lands in and near Luss on the western bank of Loch Lomond, about 31 miles north of Glasgow.

The Colquhouns acquired extensive lands in the region during the 13th and 14th centuries via a combination of grants and marriage.

In the early 15th century the Colquhouns filled a local power vacuum by acquiring control of Dumbarton Castle.Subsequent significant events are summarised below.

  • Ian of Luss ( Clan Chief) was murdered by Macleans of Duart.
  • In the 15th century the 11th chief built the castle of Rossdhu on the banks of Loch Lomond, the ruins of which still exist.This chief achieved high political office while his son became Bishop of Argyll.
  • In 1603 a force of 400 MacGregors defeated a force of Colquhouns an event which resulted in outlawing of Clan Gregor,
  • In 1774 construction of the Rossdhu Mansion (image no 2 below) began. This is still owned by the Colquhouns but leased to a golf club.
  • In 1873, the 11th baronet of Luss was drowned in Loch Lomond together with a number his men when a boat capsized after a hunting expedition on an island in Loch Lomond.
  • Sir Ian Colquhoun the 31st chief who died in 1948 is remembered for his conservation work and leadership of heritage organisation, National Trust for Scotland.

Luss is a conservation village popular with locals and tourists.
