Hi
The baptism could have taken place sometime after he was was born, I have seen them done in job lots with a range of ages, ie if he was a year old when baptized, it would have been registered in the previous year

One of my relatives was not baptised until he was 26 and about to marry. Thankfully the clergyman added a note to show when he was born - but a search on Ancestry really confused me initially until I looked at the actual record
