Among the most important of modern documents associated with Christ Church Cathedral are the registers of baptisms, marriages and burials which stretch from 1710 into the present century. Apart from being an important genealogical source for the 18th century, a period for which few registers exist, these documents reveal a great deal about the relationship between the cathedral and the society which it served. They enable the historian to chronicle the changing fortunes of the families most associated with the cathedral and as such act as a mirror of the world of Protestant Dublin in the 18th and 19th centuries.
