Liam in Hebrew is "my people or My nation" it is my son's name....Laura
Liam pronounced LEE-am is a boy's name used in English and Irish Gaelic. It means a "Determined protector." It is actually a variant of William. I don't know if there is a Hebrew meaning.
Liam isn't a Hebrew name. It's Irish Gaelic meaning determined Guardian or "Helmeted", it derives it's meaning from the name Wilhelm or William which are pronounced "Will-Helm" and "Will-LEE-am"
