If you ever wondered why a large number of your ancestors seemed to disappear during a certain period in history, it may have been due to an epidemic. Epidemics have always had a great influence on people and therefore the genealogists trying to trace them. Many cases of people disappearing from records can be attributed to people dying during an epidemic or moving away from the affected area.
