Eileen:
I searched the subscription site FindMyPast.ie and did not find a Philip McBride baptismal record in Co. Tipperary. I also looked for a Catherine Ryan baptismal record in Gortnahoe since marriages were normally held in the bride's parish and the only Catherine Ryan baptismal records in that parish were in 1815 and 1818 which appear to be too early for your purposes. Here is the link to the parish register in case you want to search manually.
