According to my great uncle, my great grandfaher said that his g-g-grandfather was a Jacobite captured at Culloden and transported (rather than executed b/c of his youth) to America. I'm still in the process of finding the connection of my earliest traceable American ancestor to that lucky Scotsman. I've gotten as far back as 1766 in PA. Although I haven't made the connection, yet, I have also not found anything that disproves my g-grandfather's claim.
