I have an Edward Fullerton, son of Alexander Fullerton, married Mary Coyle in Carndonagh 8 Feb 1871. Edward's address is given as Minaward. There is no Address given for Alexander. Mary & Edward had 3 children, Mary Ann b 1872 in Buncrana district, Alexander b 1880 in Derry and Bridget b 1879 in Derry. Does any of this fit with you?
