Waterford and Mothel and Rathgormack Parish Marriage Records

Hi everyone and a happy year.  I have been trying to find the marriage record for John Power and Ellen Rochford circa 1838 - 1844, should be somewhere in the vicinity of Carrickbeg (where first child Edmund was bap. in Dec 1843) or Carrick on Suir. The marriage does not appear in the CoS or Carrickbeg registers so i have been searching all the surrounding areas with no luck.  However the online marriage registers for Mothel and Rathgormack that i can find are only those for the period 1845 -1880, so this remains a possibility.  Does anyone know if the earlier marriage records for these parishes are available please.
