Thank you so much Elaine for your prompt reply, I have also had a reply from Sue S. who tells me that William Henry's birthdate is 25th January 1852 which makes sense of the baptism date.
Once again many thanks.
Before I change it in our database I decided to check which quarter he was registered
to help settle the issue and I can not find a birth reg. Would you mind seeing if you can find one please. Two sets of eyes are better than one. LOL.
