What does the baby name “Dillon” mean?

Dillon is a warm, easygoing unisex baby name with Irish surname roots that trace back through Norman France to the ancient Viscounty of Leon in Brittany.

Origin of the baby name Dillon

Dillon comes from the Irish surname O Dilliuin, itself thought to derive from the Norman French family name de Leon, brought to Ireland by Sir Henry de Leon following the Norman presence in Ireland during the 12th century. That Leon connection traces back to the ancient Viscounty of Leon in Brittany, making Dillon a name with a surprisingly international journey: from Breton Celtic territory, through Norman French nobility, into Irish family tradition, and finally into use as a given first name. It is notably unrelated to the Welsh name Dylan, despite the similar sound.
