History & Origin

Dillin is a spelling variant of Dylan, a Welsh name tied to the sea and usually glossed 'great tide' or 'son of the sea'. In the medieval Mabinogi, Dylan is a figure connected with the waves, and the modern name spread widely for boys in the late twentieth century.

This -illin spelling always stayed rare beside standard Dylan, cresting in the early nineteen-nineties. It reads as a contemporary variant rather than a vintage name, keeping Dylan's sea-linked meaning.

Did you know? Dillin rode the boom in Dylan as a boy's name; this spelling reached its small peak around 1992 at only a few dozen boys a year.
