I found CowHampshire's reference to my blog today humorous, but all things considered, I am probably not related to Vlad the Impaler (Dracula), or his father Dracul. It's more probable (but still unlikely) that one of my ancestors was one of 'the impaled'.
But I did just discover there are some who claim that the British Royal Family are direct descendents. (Site claims Charles is Dracul's 16th Great Grandson...through Dracula's brother Vlad (the Monk).
Not too surprising since the royal lines of Europe are known to have intermingled. But perhaps reason for the British to be a little worried.
