Thank you all for your help. So it looks like a careless priest at that time! I have search under many spelling and every marriage on that date but no luck.
If I can explain my brick wall ... the family I started researching were that of John Killoughery born 1851-1856, don't know where. The only address for him is Ballyea although he doesn't appear to have been baptised there. He married Mary Blake in 1882 and went on to have 13 children of which I have identified 12. His marriage cert states his father to be Michael, a farmer, still alive in 1882.
As I was having no luck finding the father Michael I am trying a sideways approach.. ie John is likely to have a brother Michael but I've now found 3 possible brother Michaels

:
Michael born 1861 married Mary O'Laughlin approx 1890 - CANNOT FIND MARRIAGE
on both census his father Michael is living with them. also CANNOT FIND HS BIRTH.
Michael born in the range 1841 - 1851 who married Bridget Neylon on 12 Feb 1878 according to parish record. They lived Ballyfauden and had 7 children I can find (although he says 6 in 1911 census.. one pair of twins in 1882 so maybe one died at birth??) CANNOT FIND HIS BIRTH so no idea of father... as patrick_a says maybe John (or Patrick?). Witness at his marriage was Dan Killoughery again.
Michael born 1842-1844 marries Anne Grice? c 1872 (found a marriage 1873 with a Dan Killoughery as witness??) They had 7 children with 2 dying. Have only found one of them so far. Lived at Moymore North, Kilaspuglonane.
another Michael marries Bridget Scanlon in 1870 and I have found 3 children of theirs, Norry 1888, John 1881 and Ellen 1878.. (patrick_a - so I think this is a different Michael)
So all this just to find out who John's parents are!!! If anyone has any inspiration, please guide me. I have no Irish connection (John's g-grandaughter lives here in sunny St Annes, Lancs) so the geography and the pronunciation of the names is alien to me!!
Many thanks
