Clans & Septs

People often ask ‘What is a sept?” This is a good question since many people are confused by the words “clan”, “family”, and “sept” when these terms are used to describe the Scottish Highlanders and their way of life. They also ask questions such as “Is a family different than a clan?” and “How did septs come into existence?”

A clan or family is a legally recognised group in Scotland, which has a corporate identity in the same way that a company, club or partnership has a corporate identity in law. There is now a belief that clans are Highland and families are Lowland but this is really a development of the Victorian era. The Lyon Court recognises both the clan and the family as being the same thing now. Scottish clans, as we know them today, were beginning to be formalised at the time of Robert the Bruce in the early 14th century. Since his time, the number of clans has multiplied dramatically and nearly all these later clans started out as septs.

A sept is a family name that can be related to a clan or larger family for various reasons. Usually this came about either through marriage or by a small family seeking protection from a larger and more powerful neighbour. Nowadays, this relationship is most often seen in the clan tartan that individual families are entitled to wear.

“Sept” is actually a term borrowed from Irish culture in the nineteenth century to explain the use of a variety of surnames by members of a single clan. Where Scots would say “MacGregor and his clan” an Irish historian might say “O’Neill and his sept”.

Over time, many septs have become clans in their own right and, in the political turmoil that Scotland has seen over the centuries, many others came to be related to more than one clan. There is no official list of which septs belong to which clans. There also is a tendency for clans to try to claim as many septs as possible but for status.
