Meaning and origin of Dylan
Dylan is a Welsh name that is usually said to mean “son of the sea”.
Dylan comes from Welsh legend. In the Mabinogion, Dylan ail Don is a son of Arianrhod who takes to the sea as soon as he is born, and his name is often explained as "son of the sea" or linked to Welsh words for a great tide, though the exact etymology is debated. The name stayed largely Welsh until the poet Dylan Thomas made it famous in the twentieth century, and the adopted surname of the songwriter Bob Dylan carried it further. It is now well established across the English-speaking world. Dylan feels modern yet rooted in myth. It is used mostly for boys and occasionally for girls.
Other spellings with the same sound: Dillon, Dillan, Dillen.
