Hi John,
It's a long time since I looked at that film - perhaps the entry also said son of?
Yes, you are right about the forenames for the Ballaragh Skillicorns, but wouldn't the uncles have been given as Henry and John (eldest first - especially as Henry was the heir) rather than John and Henry?
Far too many same name Skillicorns and missing mothers, as well as all those gaps in the register!
