What is the date & place of birth of the son whose birth certificate he is named on?
If you want specific help on this person, you will need to give his name, name of wife & their approximate dates of birth, name of son & any censuses you have found him on [preferably with the census reference].
For general help - the sites most commonly used [free] freebmd, county bmd sites, familysearch.org [pay] findmypast - who have deaths at sea & other 'abroad' events, ancestry & NBI for burials. Some RC mambers have local family history parish records transcriptions on CD.
