I belong to a clan and there are many advantages to belonging to a clan. Mine has a very experienced genealogist to help us with our lines. We can exchange information with others of the same line. That is only two reasons, both good. And I have found more good reasons to join a Clan Society. Choose the clan name that you want to learn more about and find out for yourself. I choose my family name since my grandfather and his family immigrated from Scotland but then I learned of the names of all my Scottish grandmothers.
What the others have said about clans is true but don't let it prevent you from joining a society as there are benefits from joining. You can learn more and you can help others who may be stuck on your line. My email is Wstjs@aol.com
if you want to write to me.
