If you have based the date of birth on information that is on the censuses and parish records, I would not consider that as being fact. The same applies to the names that appear in these records.

You must appreciate that things were a lot different 150 years ago than what they are today and many were unable to read and write. In most cases the accuracy of the ages given would depend on how good the memory of the person supplying them was. There was no going to the filing cabinet to get the birth certificates to look at.

Places of birth on censuses can also be misleading sometimes, simply because they did not know and they were guessing. My own father always told me he was born at Drybrook but on his birth certificate it is stated as Ruardean.

In the 1841 Census the ages were rounded down to the nearest five for those aged 15 or over.

The above also applies to the spellings of surnames. An example of this is with some of my own ancestors whose surname was WOAR but it has also been written with variations of WOOR, WOORE and HOARE on the original records.

My advice is to use information on old records as a guide only and not as absolute fact.
