Born in 360, the son of a Christian British chieftain, during the reign of Constantius Caesar, Ninian went on to become the missionary to the Celts and Picts. As a young man, Ninian 'was instructed' in Rome and made bishop there. During his return to Britian he met and befriended St Martin of Tours who sent stone masons onwards with him. Around 397 They built a white-washed stone church at Whithorn, Galloway which would become the base for his mission to the Southern Picts and in time, a leading monastic centre. It is generally acknowledged that the missions of Ninian and his followers prepared the foundations for the work of Kentigern and Columcille. For more, read here.
