History & Origin

Dilan is a phonetic spelling of Dylan, from the Welsh elements dy (great) and llanw (sea, tide) or dyn llan (person of the sea). Dylan Eil Ton was a divine figure in the Mabinogion, the great collection of Welsh mythology. The name carries powerful oceanic imagery.

The Dylan spelling became internationally famous through singer-songwriter Bob Dylan (born Robert Zimmerman, who took the name in tribute to poet Dylan Thomas). The Dilan spelling appears in Turkish and other cultures as a completely separate name meaning like a lion or brave. In the United States, Dilan is used as a variant of Dylan.

Did you know? In Welsh mythology, Dylan Eil Ton (meaning Dylan Son of the Wave) was a sea deity who at birth dived into the sea and could swim as well as any fish. Every wave breaking on shore was said to be weeping for Dylan, making the name one of the most poetically charged in the Celtic mythological tradition.
