Lordship of the Isles

A student query set 'Whittaker' thinking.  What reliable info can be quickly sourced?

• BBC Scottish History - looks useful.  http://www.bbc.co.uk/scotland/history/articles/lords_of_the_isles/
• The UndiscoveredScotland website has a nice factual overview with lots of dates.
• Book in the Whittaker Library - I. F. Grant, The Lordship of the Isles
• A selection of Scottish history books in the Whittaker Library

Be careful when Googling for info.  Sometimes you wonder how impartial a website might be.  If there are adverts totally disconnected with the subject-matter, or references to the author being a member of various web-circles, you are right to be wary.
