Like with anyone you are researching you work backwards finding every real record they generated during their lifetime so if they have primary records eg his marriage and secondry records like census which you say shows some conflicting infomation ( as it is given or assumed information in census ) then if I was researching I would be looking for passenger ship records in the US and finding primary information of his name used which is cross referenced with his ID when he booked, the date he travelled, who he travelled with, where from and which ship...some have information about last address before travel, nationality and it helps to know what religion he was, so it gives some starting point.... but many Irish travelled from English ports and many English travelled from Irish ports and there is no passenger records between Britain and Ireland back then or now
It is impossible to blanket search Ireland or England........many assisted emigrants came from Ireland and Britain especially during that time which means the US was flooded with immigrants from Britian/Ireland.
In Ireland alone there are 32 counties and more than a thousand parishes. It is possible to find dozens of people by the same name and in the same time period as this person.... easier to find in Britain ( England) because of civil birth records started eariler and census is available but still a very difficult task, both places it would at this point with limited information an impossible task and it would be down to what 'fits' and that is not research it is guess work
