Cillian

Cillian is an Irish name with an early saintly history. One proposed derivation connects it with the Old Irish word for a church and a diminutive ending; other explanations have also been suggested. “Little church” is therefore a possibility rather than an unquestioned translation. Saint Cillian’s association with Franconia gives the name a historical connection beyond Ireland.

The Irish spelling begins with a hard k sound, which may need an initial explanation to English readers. Killian and Kilian make that sound more obvious while preserving related naming traditions. Parents drawn to Cillian can compare Declan or Ciaran for other Irish choices, but each has a separate history and should be considered on its own.
