Blue banana, That's excellent work. I've dropped the idea of a Donaghmore link. From the birth register for son Daniel, which you located, they were living in Tureen (or Tooreen), before moving to the Blackpool / Commons Road area. I'm only aware of Timothy now for the first time. If it's a church record, Mourneabbey is the church, which is the parish.
Thanks for all your help.
