Highland Clans

Clan Fraser

Clan Fraser (Scottish Gaelic: Clann Frisealach, French: Clan Fraiser) is a Scottish clan of French origin. The Clan has been strongly associated with Inverness and the surrounding area since the Clan's founder gained lands there in the 13th century. Since its founding, the Clan has dominated local politics and been active in every major military conflict involving Scotland. It has also played a considerable role in most major political turmoils.

Around the reign of William the Lion (r.1165-1214), there was a mass of "Norman" immigration into Scotland. Thomas Grey, a 14th century English knight, listed several "Norman" families which took up land during William's reign. Among those listed, the families of Moubray, Ramsay, Laundells, Valognes, Boys and Fraser are certainly or probably introduced under King William.

The earliest written record of Frasers in Scotland is in 1160, when a Simon Fraser held lands in East Lothian at Keith. In that year, he made the gift of a church to the Tironensian monks at Kelso Abbey. The Frasers moved into Tweeddale in the 12th and 13th centuries and from there into the counties of Stirling, Angus, Inverness and Aberdeen.
