Meaning & origin

Dyllen is a modern respelling of Dylan that first appeared in U.S. birth records in 1992, reflecting the late 20th-century trend of creative name adaptations. Although it has never entered the top 1000, the name reached its peak popularity in 2009 (the peak year in its trajectory). Its trajectory has since remained stable, with a steady but low level of usage. The spelling Dyllen offers a fresh take on the well-known Welsh classic.

Dyllen is a modern spelling variant of Dylan, a name of Welsh origin from the elements 'dy' (great) and 'llanw' (sea), traditionally meaning 'son of the sea'. In Welsh mythology, Dylan was a sea god. The spelling Dyllen emerged in the United States in the 1990s as part of a trend of creative respellings. It is used almost exclusively for boys.
