At Ayton, in Berwickshire, we find St. Abb's Well, recalling Abb or Æbba, who, in the seventh century, presided over a monastery on the headland still bearing her name, and in whose honour the priory at Coldingham was founded by Edgar, son of Malcolm Canmore, some four centuries and a half later. Her monastery on the headland was founded by Aidan, who was sent from Iona to the North of England in response to a request from King Oswald, of Bernicia, for a missionary to preach Christianity to his pagan subjects. This was about the year 635. Aidan made the island of Lindisfarne, off the coast of Northumberland, his head-quarters. It is still known as Holy Island. Aidan has not been forgotten in the matter of wells. There are four to him, viz., at Menmuir and at Fearn, in Forfarshire; at Balmerino, in Fife; and at Cambusnethan, in Lanarkshire. This last, called St. Iten's Well, was noted for the cure of asthma and skin-disease. Boisil, abbot of the monastery of Old Melrose, about the middle of the seventh century, still lives in the name of the Roxburghshire village and parish of St. Boswell's. There is a spring in the parish bearing the name of The Well-brae Wall. Boswell's own spring is popularly styled the Hare-well. Not far from both is St. Boswell's Burn, a tributary of the Tweed. The local fair held on July 18th, in honour of the saint, used to be a notable one in the border counties, and was frequented by large numbers of gipsies who set up booths for the sale of their wares. Bathan, who flourished in the early seventh century, had to do with Shetland, and with the region about the Whittadder, in Berwickshire. Abbey St. Bathans, in the latter county, is named after him. His well is on one of the haughs beside the river, not far from the ruined nunnery. Its water is believed never to freeze. Boniface belonged to the same century. He is said to have preached Christianity at Gowrie, in Pictavia, and afterwards at Rosemarkie, in the Black Isle, where he died at the age of eighty, and was buried in the church of St. Peter. A well and a fair at Rosemarkie still keep alive his memory.
