Hi I'm posting here cause I don't know where else to post it.

I was wondering if anyone could tell me what exactly is a clan sept? I have tried to find info on the internet, but I'm still not quite clear on what it means. If I have a name that is listed in the septs of a clan, does it mean that our descendants worked for (were employed by) that chief, were they for lack of a better term "subjects", relations or did they just happen to live in the region governed by the chief?

Thanx
