I found this in an offshoot branch of the family tree. Very interesting. I'm sure there was more than one Flora Macdonald on Skye, but the dates match with the '45 and her suffix "the Heroine" suggests this is the one in the stories about Prince Charlie.

I've found quite a lot of Macdonalds in the tree - looks like another kilt option to me.
