Sue:
Welcome to Ireland Reaching Out!
I located the 1834 marriage record in Gowran RC parish in Co. Kilkenny. See transcription below. Also located the baptismal records for Edmund and Catherine but Michael and Johanna did not come up. Here is a link to the parish register for Gowran/Clara parish http://registers.nli.ie/parishes/0978 I would search the register for the other two records.I also located an 1803 baptismal record for a Roger Cummins in Clara. The father was shown as Michael but the mother was Mary Sharp.
Looks like the family lived in Gowran which is in northeast Kilkenny not far from the Co. Carlow border.
Let me know if you have any questions.
