Keeping Historic Data - An HR Management System

I am trying to design a database for an HR management system.
I am not very clear on how to handle historic employee data in this database and will need some help and advice please. Any comment you can provide, i'd really appreciate it.

We will like to have record of historic data and the date of change:
Employee address change
Employee name change
Salary change
Position/Title change
Office location change
Number of dependents change
Bonus received year-to-year

E.g. if an employee name changes, we should still have to have a record of what the old name was.
Scenario:
Jacqueline Peters got married 2years after her employment date and now goes by Jackie Harrison (the changed was made on the system), she leaves the firm 10years later. Many years later, someone calls about a Jacqueline Peters that worked here, we have no way of knowing who that is.
Now, we would like to the salary she was earning 5years after she started here though her endsalary has changed 10years later she got a big promotion (salary change) and changed department, we have no way of knowing what her salary at a particular time was and what her old title was.

What's the best way to design this database to handle historic data? Have you worked on something similar? How did you go about it?
Any ideas and comments will be greatly appreciated.
