Use this handy ready reckoner to help you work out the ages and dates of birth, marriage and death of your ancestors.

By simply lining up the detail you know and rotating the wheel (either the smaller or the larger wheel) the age or required date will be revealed.

This is so much more handy than messing about with a pencil and paper. And measuring just 12cm in diameter (nearly 5 inches) this slim little gadget will easily slot in your notebook or handbag, so that it’s always within easy reach to use.
