Dyllan is Welsh in Origin.

Dyllan is a modern respelling of the Welsh name Dylan, rooted in dy “great” + llanw “tide, flow,” giving the sense “great tide” and, by poetic extension, “son of the sea.” In medieval Welsh lore, Dylan ail Don is a sea-affiliated figure whose birth tale says he rushed to the sea at baptism, cementing the name’s maritime imagery. Revived in Wales in the 19th–20th centuries, the name spread widely through the influence of the poet Dylan Thomas and later gained transatlantic momentum via Bob Dylan.

While Dyllan is uncommon, it follows contemporary trends for creative spellings and is used for boys and, increasingly, girls, typically pronounced DI-lən. Close variants include Dylan (standard Welsh/English), Dillon (Irish-influenced), Dillan/Dyllon, and Dilan. Feminine elaborations such as Dylana also appear. All forms retain the core association with the sea and the idea of powerful flow or impulse.
