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 (will, desire) and helm (helmet, protection), thus carrying the broad sense of resolute protector. The name entered Ireland through Norman influence following the twelfth-century invasion and gradually became thoroughly naturalized in Irish culture. It rose to widespread international popularity in the late twentieth and early twenty-first centuries, becoming one of the most common boys' names in English-speaking countries. Related forms include William, Wilhelm, Willem, Guillaume, and Guillermo.
