Karen, I suspected Sutton hadn't read your initial post correctly !
As to the age difference, it was very common for Irish men to be a bit 'long in the tooth' when they married, expecially if they had emigrated. This was because they were expected to 'send money home' to the family in Ireland.
Take my Irish for example -
Patrick Dunn was born circa 1817 in County Mayo
He came to England circa 1845,
He married Mary NcNulty in 1850 when she was just 17, and also from Ireland.
As these immigrants were usually illiterate, they could only guess at their actual age, so there were always discrepancies between Census returns and certificates, sometimes huge ones !!
So, as I said, the choice is yours, follow up the info you have, or start another search. If it were me, I would do the former, just to make sure, if nothing else.
