No sign of the poem but a genealogy site (which you may well have see) came up with this:

Sometime after the St. Vincent church in Ballyferriter was built, a Peter Golden wrote a poem about it, titled, "Marry me in Ballyferriter". A Connie Foley put the words to song. Does anyone out there know the words? Thank you. Margie Murphy Monihan

There was no reply to the query.
