The records in this volume are those of the Diocese (as opposed to the Ecclesiastic Province) of Dublin, an ancient jurisdiction which today encompasses all of the city of Dublin and County Dublin, as well as parts of Counties Carlow, Kildare, Leix, Wexford, and Wicklow. In addition to the Acts or Grant Books and Wills of the Consistorial Court, the records indexed include licenses, letters, powers of attorney, and a variety of other will or probate records, such as wills copied in the Chancery and Exchequer Inquisitions of Dublin, Kildare, and Wicklow. Moreover, of the nearly 60,000 records indexed (referring to about 100,000 people), nearly half are marriage licenses.
