In the 17th century natality and mortality was managed by the church. The church had all the records of the people that have been born in that period of time, and of the people that had died (and how did they died; if they had a disease or something in between those matters). A historian that is doing some research about the diseases of a specific population would find this information very important; because by reading the funeral records he could come to a conclusion.
