During the early modern period, the city of London produced weekly mortality reports called bills of mortality. These bills—printed from 1603 onward—detail the number of deaths per parish; plague deaths per parish; and deaths citywide by cause of death. However printed bills were actually summaries of manuscript bills produced for the monarch, which contain a parish-by-parish breakdown of every cause of death throughout the city of London for the preceding week.

Samuel Pepys is primarily remembered for his decade-long diary, which recorded major events in 17th century English history including the Great Plague Outbreak (1665).1 Just before the height of the plague, on September 7, 1665, Pepys wrote in his diary, “[I] sent for the Weekely Bill, and find 8,252 dead in all, and of them 6,878 of the plague; which is a most dreadfull number, and shows reason to fear the plague hath got that hold that it will yet continue among us.

In late November of 1703, a “great storm” or hurricane struck the British Isles. Bad weather began a few days before the heart of the storm made landfall on November 26th, spawning tornadoes, ripping off roofs and chimneys, and destroying entire fleets. One of the most famous tragedies of the storm happened on the Goodwin Sands, a deadly sandbank off the coast of Kent. At least 53 ships were wrecked on the sandbank and over 2,000 men died just six miles from safety.

The Bill of Mortality from Christmas week in 1664 reports that three people died in the parish of St Foster. But fifty years later, there were happily no Christmas deaths in the parish of St Vedast—or rather, the parish of “St Vedast alias Foster.” Because the parish of St Vedast is the parish of St Foster. Welcome to the complex world of early modern parish names. Given that our sources were published over the course of centuries, it’s hardly surprising that the names of some of the parishes in the bills changed over time.

One of the more helpful digital databases for the study of early modern history is Early English Books Online (EEBO), which contains images of most of the surviving books printed in England between 1473 and 1700. It builds upon the cataloging work of 19th-century bibliographers and began its life as a collection of microfilm in the late 1930s and 1940s before being digitized at the turn of the twenty-first century.1 Because its focus is on books rather than broadsides or bills, EEBO only contains a small fraction of the early modern Bills of Mortality but a keyword search for the bills still turns up almost 500 results.

The main organizational unit behind the London Bills of Mortality is the parish: a religious administrative unit usually consisting of one or more churches, their associated staff, and all Christians living within the geographical bounds of the parish. The parish clergy christened, married, and buried their parishioners and—starting in the sixteenth century—the parish clerk kept a register of those events. The burial numbers would eventually form the basis of the bills, with christenings added later.
