Hi Renee,
The marriage record is on rootsireland but has very little info!:
Date of Marriage:14-Nov-1847
Parish / District:Enniscorthy
County:Co. Wexford
Husband
WifeName:JohnBarry
JoannaFurlong
IF John was also from Enniscorthy (marriages were usually in the bride's parish) this is the only Ennioscorthy baptism:
Name:John BarryDate of Birth:
Date of Baptism:28-May-1822Address:
Parish/District:EnniscorthyGender:MaleCountyCo. Wexford
Denomination:Roman Catholic
Father:John BarryMother:Johanna Bryan
Another clue would be the name of John's first son. With the Irish naming pattern the first son was named after the father's father so maybe there was a long line of Johns
Annoyingly I couldn't find a Joanna baptism in Enniscorthy!
The Tithe Applotments have 7 Furlongs and 2 Barrys in Enniscorthy Wexford 1833 (free at titheapplotmentbooks.nationalarchives.ie/)
The Natnl Library of Ireland has made the R C registers freely available to search at registers.nli.ie/. If you search for Enniscorthy you'll find that the records for Enniscorthy are considerable - more than most and from an early year.
