[_Apologie pour la Maison de Nassau._ Madril, 1664.] Prince William (born 4th November 1650, died 8th March 1702) was the son of William Prince of Orange and the Princess Mary, eldest daughter of Charles I. Prince William married the Princess Mary, eldest daughter of James, Duke of York, afterwards James II., and Anne Hyde. The Prince of Orange deposed his father-in-law James II., in 1689, and was declared king in his stead. William and Mary were, however, joint sovereigns, and the crowns, sceptres, and orbs were all doubled for them, and on the Great Seal they are both represented, one hand of each resting on the orb. Queen Mary died in 1694, and after that date King William reigned alone. The same coat-of-arms was used all through, but during the double reign the initials "WR" and "MR" are generally added. It is curious to note that William III. several times altered the place of the coat-of-arms of France on the English coat.

[DELPECH. _Iconographie des contemporains._ Paris, 1832.] William, Duke of Clarence (born 21st August 1763, died 20th June 1837), was the third son of George III., and succeeded his brother George IV. on the throne of England in 1830. He was parsimonious, and the economy used at his coronation was so marked that it was called a "Half Crown-ation." William IV. married Adelaide, daughter of George Frederick, Duke of Saxe-Meiningen, and their two daughters died as children.
