Clan Colquhoun Connection
Since the very earliest records, the deer-haunted hills and wooded glens and loch-side lands of Luss have belonged to the ancestors of the present Chief of Clan Colquhoun. His remote forefathers who lived there more than seven hundred years ago were most likely a branch of the ancient rulers of Lennox, and they used the surname of Luss, taken from the name of their lands. They were a sacred family, Celtic priests and hereditary guardians of the bachuil or crozier of St. Kessog: the martyr who dwelt in Glen Luss or on Inchtavannach, the "monks isle" in Loch Lomond. 
The name Colquhoun is territorial in origin from lands of this name in Dumbartonshire.  In 1246, during the reign of Alexander II, Humprey de Kilpatrick obtained from Malcom, Earl of Lennox, a grant of the lands and barony of Colquhoun, in the parish of Old or West Kilpatrick, pro servitio unius militis, etc., and in consequence assumed the name of Colquhoun, instead of his own. 

Humphrey de Kilpatrick's son Ingram is said by tradition to be the first to take the name Colquhoun.   About 1368, Sir Robert Colquhoun of that Ilk married the heiress of Luss and the clan have since that time been known as "of Luss". Sir Robert supported Bruce and fought at Bannockburn. The seat of the clan remains to this day, Rossdhu House, in Luss, on the West Shore of Loch Lomond. 

In 1603 a feud between the Colquhouns and Macgregors came to a head at the Battle of Glenfruin, the "Glen of Sorrow", the Colquhouns were massacred and as a result the Macgregors had their name "outlawed" under pain of death, by King James VI before he left to take the English throne. The Macgregor chief was caught through Campbell treachery and hanged with eleven of his principal clansmen. (check the stories page for a full account of this incident)

Sir John, 19th of Luss, was a necromancer and the last known person openly to practise witchcraft in Scotland. He became one of the first Nova Scotia Baronets and married a sister of the Marquis of Montrose. He subsequently fell in love and eloped with another of Montrose's sisters!

Perhaps one of the most remarkable clan chiefs of living memory was the late Sir Iain Colquhoun of Luss. During World War I he killed a Prussian officer with his revolver and 5 Bavarians with an improvised club. Both weapons are now at Rossdhu. Sir Iain was also noted for keeping a fairly tame pet lion in the trenches. 

Like many other clansmen, Colquhouns have scattered worldwide and many have found fame. John Caldwell Colhoun 1782-1850 was Vice- President of the United States of America, and a Lieutenant Jimmy Calhoun of the 7th U.S. Cavalry fell fighting the Sioux Indians in Custer's last stand at the Battle of Little Bighorn.

The story of the crest of a stags head and motto "SI JE PUIS" originates in an action by a Chief of Clan Colquhoun seizing Dunbarton Castle. In 1424, when King James I returned from his long captivity in England, Colquhoun of Luss was chosen by the king for the key post of Governor of Dunbarton Castle, the royal fortress that dominated the Lennox. Colquhoun wrote back to the king, in French, the accepted universal language of the time, "Si Je Puis" (If I Can). The Chief gathered a group of clansmen and hid them in the woods outside of Dumbarton's gates. Then he lured a red stag (deer) by the gates chased by two greyhounds. The starving garrison in the castle opened the gates to chase the stag, wherepon the chief's clansmen rushed the castle and captured it for the King.
