Parish registers arranged to a formula advocated by William Dade (1741–90), a Yorkshire clergyman, that was often used in the dioceses of York and Chester during the late 18th and early 19th centuries. Over 200 of this type of register are known. They provided much fuller information than normal parish registers, though the quality was very variable. At their fullest, baptism registers noted the infant's name, his or her order of seniority in the family, the father's name and occupation, the names, occupations, and places of residence of the paternal and maternal grandparents (and sometimes even a great‐grandparent), the date of birth, and the date of baptism. The fullest burial registers provided similar information and gave the date and cause of death and the age of the deceased. see Roger Bellingham, ‘Dade Parish Registers’, Ancestors, 15 ( Aug. –Sept. 2003), and Roger Bellingham, ‘Dade Parish Registers’, Local Population Studies, 73 (2004).
