Irish diminutive of William (Uilliam), from Germanic 'wil' (will) + 'helm' (helmet). Global phenomenon.

Sharing the same meaning

Other Christian boy names from the Divine cluster

Elijah
My God is Yahweh, the fiery prophet who rode a chariot to heaven — Elijah challenged the prophets of Baal on Mount Carmel, called fire from the sky, and was taken up to heaven in a whirlwind without dying. His name burns with the absolute devotion of a man who stood alone against an entire kingdom's apostasy and won, armed with nothing but conviction and the fire of the one true God
Theodore
Gift of God, heaven's offering to the mortal world — Theodore reverses the syllables of Dorothy to create the same meaning from a masculine angle: God gives. Multiple saints and two American presidents carried this name, and it speaks of gratitude for the divine generosity that places children into families, talents into hands, and purpose into hearts that were waiting to be filled
Jack
God is gracious, by way of Jankin, a medieval English pet form of John (from Hebrew Yohanan, 'Yahweh is gracious'). Once a familiar nickname, it long ago outgrew that role to stand on its own and has repeatedly topped boys' name charts across Britain.

Thierry
People's ruler, the French form of Theodoric, from a Germanic name joining theud (people, nation) to ric (ruler, power). Borne by Merovingian kings of the Franks, it carries an air of deep-rooted, sovereign leadership across the French-speaking world.

From the ancient Greek Theophilos, a compound of theos ('god') and philos ('beloved, dear, friend'), meaning 'beloved of God,' 'friend of God,' or 'one who loves God.' The name appears at the opening of both the Gospel of Luke and the Acts of the Apostles, each dedicated 'to Theophilus' — whether a specific patron or an ideal reader ('you who love God') has been debated by scholars for centuries. It was widely used in early Christianity and among Greek-speaking Jews.

Bold people, the French form of Theobald, from a Germanic name joining theud (people, nation) to bald (bold, brave). Borne by the medieval counts of Champagne, it carries an air of noble courage, naming the daring of a whole people in one man.
