Hi Ballydw,
The marriage cert states that he was from Francis St, Wexford. However, I could not find his baptism in the parish records. There was also a James Gaul in Wexford town who married a Kate Hayes. He was also a Butcher and, like Nicholas, his father was also named James, so I suspect he was a brother of Nicholas. I am still working on it.
I am also trying to see if there was a link with a Richard & Ellen Gaul from Ballymore, Broadway, Wexford. I suspect he was.
Thanks for info on R & L.
Regards
