On the coast road north of Port William are the remains of an 11th century chapel, possibly used by pilgrims on their way to Whithorn. St. Finian was a major influence on Columba and there is evidence that he may have come from Galloway. A version of his name also recurs in other towns, such as Kilwinning.
According to an unbroken tradition dating from the earliest times and confirmed in the writings of the Venerable Bede in the 8th century, a holy man named Nynia, born among the British people, introduced the Christian faith into a significant part of the land now known as Scotland long before the coming of Saint Columba.
