Aghadowey,
I am slightly off track on this thread but I have a Samuel Torrens of Culnamen who married Sarah Morrison in Ringsend in 1871. The Torrens website states that Sarah Morrison was from Drumsurn but does not give a source for this info. I wondered if your notes make any mention of this.
Regards
Have the marriage-
Ringsend Presbyterian Church, 29 Aug.1871, Samuel Torrance, full age, bachelor, farmer, Coolnaman, son of Hugh Torrance, farmer, to Sarah Morrison, full age, spinster, Gortnagross, dau. of John Morrison, farmer. Witnesses: Saml? Miller, Jane Quigg.
