History & Origin

Dilon is a pared-down spelling of Dylan, a name from Welsh myth tied to the sea and read as 'son of the sea' or 'great tide'. The reworked spelling keeps the sound while dropping a letter, a common move as an older name spreads into new families.

Dilon never became common in United States records. It appeared in the late nineteen-eighties, peaked at only a couple dozen boys a year around 2003 while Dylan itself was booming, and stayed scarce. A boy named Dilon then is around twenty now.

Did you know? Dylan's fame owes much to the poet Dylan Thomas and the musician Bob Dylan, whose renown carried the name and its spellings, Dilon among them, around the world.
