Your pastor's wife is from the family of James of Leeston, son of John Doak and Mary Donaldson, and Ellen Daly. James m. Ellen Daly and had son William George, father of William Ellesmere. John was a shoemaker and I think Belfast has been mentioned for him, but Job's family thought he was a cousin of some sort of Job. Ellen Daly was from Co. Armagh and went to NZ specifically to marry James, which supports the idea of a connection. Job's parents were John Doak and Nancy McDowell of Ballynagarrick, but the records before that are gone. Possibly John, the elder at Newmills, could have been his father.
Margaret Atkinson was a widowed sister of James and emigrated with him eventually to Christchurch where she married William Cole.
It would be wonderful to tie these families into the Ballynagarrick tree, but I don't think the information is available.
I will send a Pm- personal message with an address.
