", in German these are Will, Willy, Bill and Billy.
In the end William comes from the first name Wilhelm (cf. Old German Wilhelm > German Wilhelm and Old Norse Vilhjálmr). Angelsaxonism should also be *Wilhelm (although the Anglo-Saxon chronicle describes Wilhelm the Conqueror as Willelm). 3 ] This is a mixture of two different elements: vil = "will or desire"; Helmut; Old Englisch Helmut "helmet, protection"; > Deutsch Helmut "knight's large helmet".
Notation and phonology Wi-[wi] is a distinctive feature of the northern French vernacular, but the pronunciations in Norman altered in the twelfth centuries from[wi] to[vi] (cf. the Norman last names Villon and Villamaux "little William"), in contrast to the Central French and Southern Norman, which transformed the Germanic William into Gui-[gwi] >[gi].
Guillaume is the modern French notation. Charlemagne's first known bearer of the name was his kinsman Wilhelm von Gellone, alias Guilhelm, Wilhelm von Orange, Guillaume Fierabrace or William Short-Nose (755-812). William is immortalised in the Chanson de Guillaume and his appreciation may explain the later fame of the name among the nobles of Europe.
Following Netherlandish legends, as mentioned by Verstegan (1550 - 1640), William was initially deduced from the Germanic name Gildhelm, which means "golden helmet" and goes back to the Romans. Later the name was adopted as the more well-known types of "Wilhelm" and "Guillaume". Gildhelm was a brave man who was given the German medal for fighting to kill the Romans.
An esteemed serviceman was raised on a sign and a gold crest of a deceased survivor was placed on his face, and the serviceman was honoured with the designation "Gildhelm" or "golden crest". For the French, the titles were Guildhaume, and Since Guillaume. Guielmus  Guielmus could also be referring to the gold tiara or the coronet of a kings, as was customary in the later era of the Holy Roman empire.
Anglo-Norman William was transferred to England after the Norman conquest in the eleventh century and soon became the most beloved name in England, along with other Norman composers such as Robert (the British relative was Hr?odbeorht), Richard, Roger (the British relative was Hroðgar), Henry and Hugh (all of Norse origins, transferred by the use of the Normans of Old French).
