Clan Colquhoun International Society (CCIS) is a 501(c)(3) organization, whose patron is Clan Chief, Sir Malcolm, 31st of Colquhoun & 33rd of Luss, 9th Baronet.

The Clan Colquhoun International Society (CCIS) aims to promote, protect, and preserve our highland heritage, the clan’s history, family and genealogical records, and make this information easily available to CCIS members.

The society is managed by volunteers, consisting of the President, Executive Director, Leadership Team, and Advisory board. Member subscription dues are primarily used to host tents at Highland games and other international events. In addition to organizing annual Clan Gatherings and other events, CCIS will assist members with genealogical research.

Clan Colquhoun International is open to all who bear the name of Colquhoun (in any form of spelling) or who are Colquhouns by birth or descent, are married to a Colquhoun or sept member, or who simply have an interest in the clan and who share the goals of this organization.
