Charles and Vlad: Royal cousins?

In a speech to help save the forests of Transylvania, Prince Charles, heir to the British throne, revealed that he is related to Vlad the Impaler, the 15th-century Romanian warlord who inspired Bram Stoker's Dracula.

According to genealogists, Charles' great-grandmother, Mary of Teck, is believed to have been descended from two of Vlad's sons.
