What information will a birth, marriage or death certificate show me?
The most comprehensive answer to this question can be found on family history enthusiast
Barbara Dixon’s website. As well as detailing the factual information, she also includes more user friendly information such as why the age on a marriage certificate should be taken with a pinch of salt and what it means when there’s a time written next to the date of birth on a birth certificate: a twin or multiple births if you’re interested!
