Church or bright-headed
Kilian is an Anglicized version of the Irish name Cillian. It is most commonly associated with Saint Kilian, a 7th-century Irish missionary bishop who worked in Franconia. The name likely derives from the Gaelic word 'cill' meaning church, or 'ceallach' meaning strife or bright-headed.
