Saint Kilian was a 7th-century Irish missionary bishop who is recognized as the Apostle of Franconia. Born around 640 in Ireland, he received his education in several Irish locations before traveling to Rome to obtain missionary faculties from the Pope. He eventually settled in Würzburg, Germany, where he worked to convert the local population, including Duke Gozbert, to Christianity. His missionary efforts concluded in 689 when he was martyred alongside his companions, Colmán and Totnan.
