 It is to the same Carteret family that Henrietta of England sent her son (the future Charles II) during the civil war in 1646.In 1657 Marguerite married Jean de la Cloche who gave his name to James.Later, finding a striking resemblance between himself and Charles II when seeing his portrait, he was convinced of being the King's son and wished to be legally recognised, like two other illegitimate sons who hence got the dukedom.
