Name

 * William is an English masculine name, from the Germanic name Willahelm, which was composed of the elements wil "will, desire" and helm "helmet, protection". Saint William of Gellone was an 8th-century cousin of Charlemagne who became a monk. The name was common among the Normans, and it became extremely popular in England after William the Conqueror was recognized as the first Norman king of England. It was later borne by three other English kings, as well as rulers of Scotland, Sicily (of Norman origin), the Netherlands and Prussia.
 * Duncan is a Scottish surname. It's an Anglicized form of the Gaelic name Donnchadh meaning "brown warrior", derived from Gaelic donn "brown" and cath "warrior". This was the name of two kings of Scotland, including the one who was featured in Shakespeare's play 'Macbeth' (1606).
