I am not a MacLean myself although, like most people who originate from the British Isles, I have Macleans in my own genealogy. On the internet there are many excellent sites about the MacLean's and their history. I will refer you to these sites rather than reproduce this information on these pages. I think that the story is best put by real Macleans. This site also sets out the different sections of the Clan and some of the famous family names like Beaton that were closely associated with the clan as Physicians or Morisons the Standard bearers.
Genealogy is one of the most important areas of the interest to the Maclean visitor.
The most active site that I have found sofar belongs to Ian Phillips and is called Mull Family Histories . Finally lets not forget the most important cymbal of Clan MacLean, its fortress on the Isle of Mull guarding the approaches to the Sound of Mull.
