Count Jefferson von Pfeil und Klein-Ellguth
His Illustrious Highness Count Jefferson von Pfeil und Klein-Ellguth (Jefferson-Friedrich Volker Benjamin Graf von Pfeil und Klein-Ellguth, born 12 July 1967) is the son of Count Friedrich-August Rüdiger Albrecht von Pfeil und Klein-Ellguth and Astrid Maria Andres.
He married Princess Alexandra of Sayn-Wittgenstein-Berleburg on 6 June 1998, becoming the husband of a member of the Danish royal family. His wife is the daughter of Princess Benedikte of Denmark, whose elder sister is Queen Margrethe II.
In Germany titles were abolished after the First World War, and incorporated into the surname. Jefferson's title in pretence is Graf, the English equivalent of Count. In Denmark, Norway and Sweden, he would be known as a Greve.[citation needed]
