Welcome to Ireland Reaching Out!
McManamon and variants were a common surname in Kilcommon civil parish. Unfortunately, the RC baptismal records for Ballycroy RC parish start i in 1885 so no baptismal record would exist for Michael.
You may want to add his story to our XO Chronicles site and possibly someone will notice a connection.
