The Lamont family are believed to have originated from Ulster, emigrating to southwest Scotland in the year 500, and are said to have been descended from Ánrothán Ua Néill, an Irish prince of the O’Neill dynasty.
Until the 13th century, the clan were known as the MacKerrachers. However, after being granted lands through a charter signed at Paisley abbey by Sir Laumon, changed the clan name to its modern alternative Lamont.
During the Scottish Wars of Independence, the Lamonts sided against the Bruces and after Robert the Bruce’s rise to the throne, they were punished and eventually lost their hereditary seat at Dunoon in 1371 to the Campbells.
The Campbells would continue to take Lamont territory and by the end of the 14th century, almost all the Lamont’s territory in the area had been lost.
This would signal the start of centuries of hatred between the two families with scuffles common as the Campbells often tried to assert their dominance as the leading clan in Argyll over the Lamonts. The fighting would eventually culminate in the dreadful Dunoon Massacre of 1646 where men of the Campbell Clan would mercilessly murder numerous Lamont men, women, and children. In 1661, the ringleader of the Dunoon Massacre, Sir Colin Campbell, was brought to justice. He stood trial on charges of High Treason, was found guilty, and then beheaded.
After that horrific event, the clan were virtually incapacitated and lacked the numbers to become involved in any major events such as the Jacobite Uprising in the 18th century. The clan does still retain a chief, the current person to hold the title is Peter Noel Lamont of that Ilk, Chief of the Name and Arms of Lamont.
