I noted that while Joseph Rowe and Ann Watkins were married in Templeshanbo, which was probably her home parish, he lived in Killane area, which would mean any children born to them would have been baptised in the Killane area.
Have you tried Killane and Kilegny C.of I. church records for baptisms.Killane, at one stage, kept the original record book there. Their records go back to the latter half of the 1700's.I have personally seen that book. It has since been transferred to a central C.of I. location.It is my understanding that the minister of Killane has a copy of those records. Kilegney records do not go back that far as it is not as old.
You might be able to get an email address online by looking up those churches.I believe they have beengrouped together.
