Upcycling is all the rage these days, even when it comes to baby names! Kilean, a close cousin of Killian, is a boy's name and a modern American reimagining of the Irish name Cillian. What could be more original than mixing Gaelic with a splash of avant-garde spelling? Kilean means "small church," from the Irish words cill, meaning "church," and ín, meaning "small or little." In the Irish language, many names bear the suffix “ín,” which is affectionately used to denote a child or the youngest member of a family. No doubt Kilean will be apple of your family’s eye and doted on accordingly!
