Hi Scott, Romilly's & George's account of what is required to establish a New Chief in their book was updated in Feb 2002 by then Lyon Blair. The new updated requirements as Todd pointed out can be found here http://www.clan-duncan.co.uk/clan-re...derbhfine.html

However the one thing that does not appear in the ruling is that any new Commander/Chief must be a resident in Scotland for over 3 years.
