John Sinclair, of Exeter is said to be an ancestor of Prince Harry's fianceé Meghan, Duchess of Sussex.
There's an interesting background story here because John Sinclair was a Scot, captured at the Battle of Dunbar in 1650 fighting from the Crown against Oliver Cromwell.
She also said to be a descendant of John Bean, Sr. (I). Same story.
Some people might think the story is even better. There's an internet version of John Sinclair's ancestry that says he was a son of Henry Sinclair of Lybster so a great grandson of George Sinclair, 4th Earl of Caithness. As tempting as it, this is no more than a guess. There is no evidence.
