About Liam
Liam is an Irish short form of Uilliam, the Irish form of William; the familiar “resolute protector” gloss is a traditional gloss rather than a literal one and belongs to the wider William name family. Its short, two-syllable shape helps explain why Liam works as both a heritage choice and a current U.S. favorite.
