Ah Sept...a Victorian invention, but no doubt here to stay, the Sept lists made up by the historian William Forbes Skene in his book of 1837 neatly and in true Victorian romanticism of the time, neatly divides up names that may have had a connection to a clan. It certainly doesn't mean all of that particular name by any stretch of the imagination and clans did, or should I say, Clan Societies made the most of the sept list created by him to bolster their membership numbers.

It would be worth reading the short article I created for a bit more detail, it will also demonstrate why Lyon Court does not have any official 'sept' list
