Denis Murphy from Kilmoney

Mary:

Kilmoney civil parish corresponds to Carrigaline RC parish. Baptismal records for Carrigaline start in January 1826  https://registers.nli.ie/parishes/0025  so it appears there would not be a baptismal record for Denis based on the years you listed. Do you have any information on his mother's maiden name so we can look for sibling baptismal records on the free site irishgenealogy.ie

Ok, thanks. Does that also include church records? He was Catholic. I have been looking through St. Finbar south records, but I’m not sure if that’s where he would have been baptized. Unfortunately, I do not have his mother’s name and also not certain of his father’s name which makes it difficult. 

Mary:

The Carrigaline records are the church records for the area for Kilmoney civil parish. Without having the names of the parents, it would be very difficult to find potential younger siblings. Have you considered DNA testing? You may have matches with 4th cousins who have more information on the family.
