How Do You Trace a Family Before Official Records? The Church Wrote It Down

English parishes were ordered to keep such records in 1538 by Thomas Cromwell, acting for the crown during the break with Rome, and the reasons given were practical rather than spiritual. Recording baptisms established age and legitimacy, which mattered for inheritance and for claims to property. Recording marriages established which unions were valid, which determined the legitimacy of children and the descent of land. Recording burials established that a person was dead, which settled tenancies and obligations. The order was resisted in places on the suspicion that it preceded new taxes, which was not an unreasonable inference. Comparable requirements were imposed across Europe over the following century, frequently after the Council of Trent required them for Catholic parishes from 1563.

The information varies enormously by period and by how conscientious the incumbent was:

• •Early entries may give only a name and a date
• •Baptisms usually name the father and later the mother, and give an occupation
• •Marriages name both parties, their parishes and from 1754 require signatures
• •Burials give a name, a date and sometimes an age or a cause
• •Some clergy added extensive comments about the people and the weather
• •Gaps occur for war, plague, neglect and periods of civil disruption

Family historians are the most visible users and not the most consequential. Historical demography is built almost entirely on these books, since counting baptisms, marriages and burials across many parishes and many years reconstructs population size, birth rates, death rates, age at marriage and family size for periods with no census. That work, conducted systematically from the 1960s, overturned assumptions about pre-industrial society, establishing among other things that western European marriage happened late and that households were small and nuclear rather than extended, which contradicted the standard account. Epidemic history is reconstructed from burial spikes. Economic history uses the recorded occupations. Climate history uses the incidental remarks.

Civil registration by the state took over the function and the transition is worth dating, since it determines which source to consult for any period. England and Wales introduced civil registration of births, marriages and deaths in 1837, Scotland in 1855 and Ireland in 1864, after which a central index covers everybody regardless of religion. France introduced it during the revolution in 1792. The new system recorded births rather than baptisms, which removed the interval problem, and included everybody rather than only members of an established church. Parish books continued alongside and are still kept, so the two overlap for nearly two centuries, and the older ones were deposited in county record offices from the 1970s onwards where they are consulted on microfilm and increasingly online.

The gaps are systematic rather than random, which matters for anybody using them. They record religious events rather than biological ones, so a baptism is not a birth and may occur years later or not at all, and the interval between the two changed over time. Anybody outside the established church is absent, which in England means Catholics, Quakers, Baptists and Jews, whose own records survive separately and unevenly. Stillbirths are frequently unrecorded. Names are spelled variably, since the clerk wrote what he heard. And the poorest and most mobile are underrepresented throughout, since a family moving between parishes leaves fragments in several books that are hard to connect.

English parishes were ordered to keep these books in 1538 to establish age, legitimacy, valid marriage and death for reasons of property and inheritance. Entries vary from bare names to extensive commentary. Historical demography is built on them and overturned assumptions about pre-industrial households. They record religious events rather than biological ones, omit everybody outside the established church, and underrepresent the poorest and most mobile.
