The Camerons of Erracht were a minor noble Scottish family and a branch of the Clan Cameron, a Highland Scottish clan. In Scottish Gaelic they are known as the Sliochd Eoghain ic Eoghian (the children of Ewen, son of Ewen).
The first representative of the Cameron of Erracht family was Ewen Cameron, son of Ewen Cameron, XIII of Lochiel, chief of Clan Cameron by his second wife Marjory Mackintosh, daughter of William Mackintosh, 13th chief of Clan Mackintosh.
Donald Cameron, 7th of Erracht was born shortly before the Jacobite rising of 1715. Thirty years later during the Jacobite rising of 1745 he joined Cameron of Lochiel and was second in command at the historic Glenfinnan gathering.
After the Jacobite defeat at the Battle of Culloden, Cameron of Erracht was a homeless warrior in the mountains for three years. He had three children, the eldest of whom was Sir Alan Cameron of Erracht K.C.B.
Sir Alan Cameron of Erracht raised the 79th or Cameron Highlanders in 1793. He was appointed Lieutenant-Colonel Commandant and led the regiment through the severe campaigns in Flanders from 1794 to 1795. In 1797 the regiment was broken up and two hundred and ten men joined the Black Watch regiment. In 1798 Cameron of Erracht raised a second 79th regiment that was seven hundred and eighty strong and after taking part in many engagements he died in 1828 in Fulham.
Captain Ludovick Cameron who was a contributor to the sporting press and who lived in Kent claimed to be the chieftain of Cameron of Erracht, however he died in 1947 without being able to establish his claim.
The Cameron of Erracht tartan was specially designed by Mrs Cameron of Erracht and is thought to have been based on an old Lochaber sett which itself had actually been based on old MacDonald overlordship.
