William

William derives from the Old High German name Willahelm, composed of the elements wil, meaning will or desire, and helm, meaning helmet or protection, giving an overall sense of resolute protector. The name was introduced to England by the Normans and became enormously popular following the conquest of 1066, when William the Conqueror became king. It has been borne by numerous monarchs, saints, and cultural figures, including the playwright William Shakespeare. Related forms include Wilhelm in German, Guillaume in French, Guillermo in Spanish, Liam as a short form in Irish use, and the feminine variant Wilhelmina.
