Edward Campbell (c1812-1860)

[jrc11]

Edward Campbell (c1812-c1860) marriage to Catherine Hunt (c1817-1905) Strokestown area.
These are my g grandparents. Dates & names from gravestone at Lissonuffy cemetery plus 1901 Irish census. I have failed to find any trace of this marriage in the Strokestown parish records  (which, to say the least are not in the best of order) or of the baptism of  any children. I believe there were at least 3 but the only one I am sure of is my grandfather, also Edward (1856-1922) The 1857 Griffiths land valuation shows an Edward and a Henry Campbell at  Coggalstack where the family were still living up until the 1930s. Any information much appreciated.
