Origins of the clan
The lands of the Clan Colquhoun were on the shores of Loch Lomond. During the reign of Alexander II of Scotland, Umphredus de Kilpatrick received from Malduin, Earl of Lennox, the estates of Colquhoun, Auchentorily and Dumbuck. The Clan Colquhoun chief's early stronghold was at Dunglass Castle, which is perched on a rocky promontory by the River Clyde. Dunglass was also close to the royal Dumbarton Castle, of which later chiefs of Clan Colquhoun were appointed governors and keepers.
The chief's title was that of the Barony of Luss which came to the Colquhouns when Sir Robert of Colquhoun married the heiress of the Lord of Luss in about 1368.
15th and 16th centuries
During the minority of James II of Scotland, Sir John Colquhoun was appointed governor of the royal Dumbarton Castle. However he was murdered during a raid at Inchmurrin in 1439. He was succeeded by his son, another Sir John, who rose to be Comptroller of the Royal Household. He received a charter incorporating all of his lands into the free barony of Luss in 1457. A year later he also received the forests of Rossdhu and Glenmachome together with the lands of Kilmardinny.
In 1474 Sir John Colquhoun was part of an embassy to Edward IV of England which was to negotiate the marriage between Edward's daughter, Cecilia and the infant James IV of Scotland. Sir John fought at the siege of Dunbar Castle which was being held by rebels and there he was killed by a cannonball.
The Clan Colqhuhoun also controlled Camstradden Castle that had been acquired by a younger son of Luss in 1395. The sixth Colquhoun Laird of Camstradden was a renowned knight and in 1547 fought at the Battle of Pinkie Cleugh.
The Clan Colquhoun lands were particularly vulnerable to clan raids due to their strategic nature. In 1603 Alasdair MacGregor, of Clan MacGregor marched into Colquhoun territory with a force of over four hundred men. The chief of Clan Colquhoun had been granted a royal commission to suppress the MacGregors. Colquhoun assembled a force of five hundred foot and three hundred horse and advanced to Glen Fruin to repel the Highland raiders. MacGregor split his force in two and while the main MacGregor force and the Colquhouns engaged in combat the second MacGregor force attacked the Colquhouns from the rear. The Colquhouns were driven into the Moss of Auchingaich where their cavalry was useless and over two hundred Colquhouns were killed. At the end of the eighteenth century the chiefs of the two clans met and shook hands on the very site of the former slaughter.
In 1625 Sir John Colquhoun of Luss was created a baronet in the Baronetage of Nova Scotia. However, in 1632 he was accused of absconding with his wife's sister, Lady Catherine Graham, daughter of the Earl of Montrose. He was accused of using sorcery and witchcraft and perhaps wisely he did not return to answer these charges. He became a fugitive and his estates were forfeited. Sir John's eldest son recovered the estates in 1646.
In 1703 Sir Humphrey Colquhoun, fifth Baronet represented Dunbartonshire in the last Scottish Parliament. He strongly opposed the Treaty of Union. He died without male issue and the title passed to his daughter's husband, James Grant of Pluscardine. However, when Pluscardine's elder brother died he re-assumed the name of Grant. He was the ancestor of the Earls of Seafield and Barons Strathspey, on whom the baronetcy devolved. The estate was succeeded to by Sir James Grant Colquhoun who was the fourth son of James Grant and Ann Colquhoun. He built the mansion of Rossdhu which remains the seat of the chiefs of Clan Colquhoun.
Clan Colquhoun today
Sir Ivar Colquhoun, 30th Laird of Luss and 32nd Chief of Colquhoun succeeded as chief of the clan in 1948. He was the longest serving chief of the clan having served for almost 60 years until his death in 2008. Upon his death he was succeeded by his surviving son Malcolm.
Sir Malcolm is married to Katharine, Lady Colquhoun. His heir-apparent, Patrick Colquhoun, Younger of Luss, was born of his first wife Susan Timmerman. Altogether there are three children. Sir Malcolm chairs the Luss Estates. In 2012, they opened the Loch Lomond Arms Hotel in Luss.
The Clan Colquhoun Society of the United Kingdom considers the following names as septs of Clan Colquhoun. However several of the names are claimed by other clans, including Clan Gregor – traditional enemy of Clan Colquhoun.
