Culdees
Culdees, either from Celtic words meaning servants of God, or from Latin ones meaning worshippers of God, were an order of irregular monks who were found in parts of England, Scotland, and Wales from the ninth or tenth century to the fourteenth or fifteenth. They have owed their remembrance chiefly to a mistaken idea that they formed a link between later times and an original and pure form of Christianity which prevailed in these countries in very early times. Many of them were absorbed into regular orders, and others were dispersed with or without compensation.
