★ What does William mean?

The story of William

William comes from the Germanic Willahelm, built from words for will or desire and for helmet. It reached England with the Normans after William the Conqueror’s victory in 1066, and stayed one of the most common English names through the Middle Ages and beyond.

In Irish it became Uilliam, and its clipped form Liam is now far more common in Ireland than William itself. The poet William Butler Yeats, who won the Nobel Prize in Literature in 1923, is the best-known Irish William.

William was a top-ten name in Ireland every year from 1964 to 1972. The most boys were named William in 1965, exactly 1,000 of them, when it was number 8. It has slipped steadily since and was number 73 in 2025. In Northern Ireland its highest place was 26th in 1997, the first year of the figures there.
