What is a Sept?
The variety of surnames within a Scottish clan do not represent separate and definable sub-clans but instead reflect the vagaries of transition of the Gaels into the English naming system as well as marriages, migrations and occupations. The main family itself may have developed a variety of surnames. The preferred modern usage is to avoid the use of the term "sept" and to simply describe these names as what they are - surnames of the family and of allied or dependent families.
