Missing Murphys in Ahalisky, Ballinascarty

I set myself the challenge of finding the vital details of all my great-grandparents and their siblings, and I have succeeded - except for this family in Ahalisky;

Finding the family was an achievement because my direct ancestor John Murphy left the county as a teenager. The only lead I have is that the daughters may have become nuns in South Africa - but I cannot find any records to support this.

I have Patrick as dead in 1921; and Thomas as dead in 1943 - both childless, both in Kilmaloda.

I have DNA results on Ancestry, but nothing connects them to this family in rural Clonakilty. I also checked emigration records, but Murphys are so numerous I can't be confident.

Where should I go from here? I feel I have hit a brick wall.
