Hi Sandra - if the offer is still on, I have a few brickwalls in Scotland as well.
Once of my ancestors actually wrote a genealogy history on the family, as well as a few other books, but dates etc don't match, and in the book Lady Flora Forbes before her marriage, was lady in waiting to Bonnie Prince Charlies mother.
Also in the book it states she was thrown out of her house by the Butcher of Culloden, and the house given to another branch of the family because they supported the English.
Also Thanistone, which is now a hotel was once the home of the Mitchell family, which was burnt down and rebuilt.
To date I have been unable to find any information on Flora Forbes.
The author's gt granddaughter, has researched the book, along with a few other branches, who have added their own notes, on records still to be searched
