Saint Modan
St Modan was the son of an Irish chieftain. He became a monk and built a chapel at Dryburgh, Scotland, in 522 which he used as a base for several years. This later became the site of a monastery: Dryburgh Abbey.
He actively proselytised on behalf of the Celtic church in the Falkirk and Stirling areas, and along the Forth, continuing until he was elected abbot, a post which he accepted reluctantly. After a number of years he resigned and became a hermit, settling in the Dumbarton area, where he would die. His relics were enshrined at Saint Modan's church, Rosneath.
