Here are several web sites you might wish to peruse:

http://www.jacobite.ca/
The Jacobite Heritage, many primary sources dealing with the Jacobites

http://www.northumbrianjacobites.org.uk/
A web site about English Jacobites (yes, there was such a creature!)

http://www.royalstuartsociety.com/
The web site of the Royal Stuart Society -- be sure to check out the "Succession" page

Hopefully this will help!

Cheers,
