Welcome to Ireland Reaching Out!
The RC records for Toomevara parish start in March 1831 which appears to be too late for records for Patrick and Anne, I did search the subscription site Roots Ireland and there were baptismal records for Maher/Meagher children with a father Matthew but none showed a mother named Bridget or a townland location of Ballybeg. There must have been a number of Matthew Meagher/Mahers in the parish.
You may want to add Patrick's story to our XO Chronicles site and possibly someone will see a connection.
