The name is said to derive from Saint Kilian, an Irish missionary to Germany in the 7th century, who, according to the Acta Sanctorum, was born in Mullagh, County Cavan, Ireland c. 640. He departed for his mission to the continent with 12 apostles from Kilmacologue in the parish of Tuosist, County Kerry, Ireland. In 689, he was martyred in Würzburg, Franconia, Germany, and subsequently became the city's patron saint.
The most likely meaning of the name is 'little church', a reference to someone prayerful or spiritual, cill meaning 'church' in the Irish language, while the suffix -ín is used affectionately to indicate a "pet" or diminutive status. Patrick Woulfe wrote that Cillian is a diminutive of Ceallach which means 'war', 'strife', or 'bright-headed'.
