William, an ancient Germanic name of great historical significance, is derived from 'wil' meaning 'resolute protection' and 'helm' signifying 'helmet'. This moniker was borne by numerous notable figures throughout history, most famously William the Conqueror who invaded England in 1066, leading to him being known as 'The Bastard of Normandy'. He went on to become the first Norman King of England. The name William also gained popularity during medieval times due to its association with Saint William of York, a 12th-century archbishop revered for his holiness and learning.
