I presume you are talking about this family
http://www.census.nationalarchives.ie/pages/1911/Wexford/Wingfield/Annagh__Middle/684236/I have found the most likely marriage

The most likley birth for Thomas is
Thomas Death born 16-Jul-1872 Wexford Ireland
Parents John Death and Fanny Kilbride
This one fits the age and looks like Thomas first son was John and one of the children was Frances.
John Death married Frances Kilbride in 1857
Registration District: Gorey
Date: 1857
Volume 6 Page 107
In the 1911 Census the family are Catholic. But that marriage in 1857 would have being protestant so perhaps the wrong assumption that Thomas is the son of John Death and Fanny Kilbride. Or else at some stage the family converted to catholic.
John Death and Frances Kilbride lived in Coolgreany, Wexford which is around seven miles from where Thomas Deathe and Sarah Dalton are in 1911 Census.
The most likely birth for Sarah Dalton is
01-Feb-1871 Wexford daughter of Andrew Dalton and Sarah Quail (her age in 1911 Census may have being wrong which was usual)
Andrew Dalton and Sarah Quail married
1865 in Gorey Registration District
Volume 17 Page 825
Interesting i found this
"Group 12 - Daltons from Parish of Kilnahue, Annagh, Gorey, Co Wexford
Bernadette Walsh, a new member of the DGS from Gorey, Co Wexford joined us in Dublin. She has traced her Dalton line back to her great great grandfather, Andrew Dalton, born in 1825 in the Parish of Kilnahue, Annagh, Gorey. His father was a James Dalton and James’s father was a Lawrence Dalton. Andrew married Sarah Quail on 12 October 1865 and they had five daughters, the middle one, Sarah born 1 February 1871 is Bernie’s great grandmother"
