Epidemic Timeframes

In case you ever wondered why a large number of your ancestors disappeared during a certain period in history, this might help. Epidemics have always had a great influence on people, and thus influencing as well, the genealogists trying to trace them. Many cases of people disappearing from records can be traced to their death during an epidemic or a move away from the affected area.
