Carol:
Welcome to Ireland Reaching Out!
I searched on the subscription site Roots Ireland and the only Catherine Parsons baptismal record in Mayo around 1853 is this 1846 record in Bekan RC parish which borders Claremorris/Kilcolman parish. There were baptismal records for three siblings: Edward, Mary and Winifred. See transcriptions below.
Could this be your Catherine?
Let me know if you have any questions.
