There is a guy (in Belgium) who claims that he is descended from Bonnie Prince Charlie's marriage to a
Marguerite Comtesse De Massillan, the only problem is,this person and the marriage never existed!
Bonnie Prince Charlie actually married Louise Maximilienne Caroline Emmanu�le Prinzessin zu Stolberg-Gedern,and from this marriage they only had a daughter;who being female could not inherit rights to the throne.
I bought (remaindered) the book "The Forgotten Monarchy of Scotland" by the self styled HRH Prince Michael of Albany.
He has since be proved to be a complete fake,obviously he has been remaindered too! LOL
Amazing what you can pass yourself of as given enough family trees,and willing victims!
