Dillon

📖 About Dillon

Dillon is a name of Welsh and Irish origin, most commonly understood as a variant of Dylan, which derives from the Welsh elements "dy" (great) and "llanw" (tide or flow), giving it the poetic meaning "son of the sea" or "great tide." In Irish tradition, Dillon (Ó Duilleáin) traces back to a Norman-Irish family that became one of the most prominent Anglo-Norman dynasties in medieval Ireland, settling in County Westmeath. The name carries a dual heritage — Celtic mysticism through its Welsh roots and aristocratic lineage through its Irish-Norman connection. It gained widespread use as a given name in English-speaking countries during the 20th century, partly influenced by the fame of gunfighter Marshal Matt Dillon from the television series Gunsmoke and the enduring cultural appeal of poet Dylan Thomas. Dillon remains a popular choice for parents seeking a name that feels both rugged and lyrical.
