Fair enough! I was more concerned about appearance than genealogy; look at some of those Mediaeval portraits of the Henrys and Edwards, and tell me if there isn't the same kind of long, thin, whippet-like look about their faces as we see with Charlie and his siblings (except the broader-faced, bulkier one, Andrew. I understand from an article in the Guardian many years ago he's never been seen in company with someone the name of Lord Glenconnor).
