Registration of births, marriages and deaths started in 1837, so before that you have to search church registers. It is very easy to make a mistake especially with clusters of families with the same surname in the same area and forenames repeated. The child's date of birth is often not shown in church registers. It's sometimes not possible to identify births for certain, so I'm always a bit dubious when people say they've gone back hundreds of years. The chances of making an error is very high.
