UPDATE: I have found what I believe to be two of Mary and Peter's sons marrying in Wexford Town and am hoping someone might have further details:
James Stafford (occupation ostler) married Mary Doyle 18th October 1872 - adddress: Wexford
John Stafford (occupation sailor) married Anne Walsh 12th May 1864 - address: John St
I can find no children for James and Mary, however John and Anne had 2 children: John (b1866) and Mary Agnes (b1870).
Any additional details most welcome
You could provide some additional details...!
Do the parish records mention a townland? Probably Rathaspeck, but that is a bit ambiguous, as that is a townland, CofI parish, and civil parish.
Which parish records - Catholic, or C of I ?
What do the two marriage records say with regard to Peter’s occupation?
Was he alive or dead at the time of the marriages?
Have you checked the tythe or valuation books?
