Dillyn

Dillyn is an uncommon feminine name that appears to be a variant spelling of Dylan or Dillon, names that traditionally have been masculine but have crossed gender lines in modern usage. With Welsh origins, the traditional Dylan means 'son of the sea' or 'born from the ocean,' derived from Welsh mythology where Dylan was a sea god. This particular spelling with the 'y' and double 'l' gives the name a distinctive, contemporary feel while maintaining connections to its Celtic roots. As a feminine name, Dillyn represents the modern trend of adapting traditionally male names for girls, often with modified spellings. The name has a fresh, spirited quality with its crisp consonants and compact form. While still rare for girls, Dillyn offers parents seeking an uncommon name with historical depth a distinctive option that carries natural imagery and mythological connections.

Dillyn is also given to boys.

Pronounced DIL-in.
