Hi Julia ive been checking the records and what these details appear to be is the modern equivalant of company registration returns. I have found so many of them for this same couple with all the same details just different years starting 1869 and ending in 1887.
I dont know how well you know the area but there is a family history centre in "Yola Farmstead, Folk Park, Tagoat, Rosslare, Co. Wexford" but when i was over at the end of november begining of December it was closed.... not sure if this is permanant or seasonal?
Hopefully someone on here might have more upto date information to help you...
Also the National achieves in Dublin has an in house team of geneologists and they are great although you will have to que and it is busy, about a 5 minute walk takes you to the national library and again they are so helpfull and waiting time for the microfishe is less than 10 minutes.
Good Luck
Mick
