Liam

Liam is an Irish short form of Uilliam, itself the Irish adaptation of the Old High German name Willahelm, composed of the elements wil meaning will or desire and helm meaning helmet or protection. The name spread widely through Ireland following its introduction by Norman settlers in the medieval period and became one of the most popular given names in the English-speaking world by the early twenty-first century. It is the Irish equivalent of William, and related forms across languages include Guillaume, Willem, Wilhelm, and Vilhelm.
