Thanks for the response.
Marriage took place on 29 Dec 1876 @ Parish Church, Carrowdore.
Agnes Jane's father is denoted as Hugh Dornan [labourer]. Agnes Jane's residence is given as Greyabbey Mills which I suspect was the Mill House beside the corn mill at Kircubbin Road, Greyabbey. She may have been in service there at the time of the marriage.
Unaware of residence of her father Hugh or of the name of her mother.
