Do my Scottish highlanders' surnames indicate that they (and I) are members of those clans?

Question

If Scottish ancestors of mine, born in the Highlands, had surnames which were the names of clans (e.g., Cameron or Ross), then can I assume that they (and I) could be considered members of those clans?

Answer 1

Today, modern Clan Associations have their own guidelines for who can be considered a member.  Historically, those of the surname or anyone who pledged themselves to the Clan Chief, were considered members of a Clan.  It's obviously more complicated than that, but it gives you an idea.  

This FAQ may help with the finer details.

A very good answer  Amy !

Plus Clans include septs which are different surnames but ones associated with a Clan . The names MacSorley, Sorley ,MacMartin ,Martin , Taylor , are just a few associated with Clan Cameron.

Then there are cadet branches .

There are five: Cadet branches to Clan Cameron Erracht , Glen Nevis , Letterfinlay, Lundarva, MacMartin , Clunes.

Each arrow in the sheaf of five arrows on the crest represent these five families .
