My grandfather was once a resident of Annaclare when his father, the widower, Henry Scott, married the widow of John Scott, Elizabeth Newton Scott in 1888. John and Henry were distant cousins. They both had children to raise and was left to manage Annaclare.
Up until the sale of Annaclare in 2010, the Johnston family resided there. A letter I received from Mrs Johnston stated she and her late husband had lived there since 1956.
Thomas Scott's death in 1955 would have marked the last Scott at Annaclare. He was the youngest sibling of John Scott and Elizabeth Newton Scott.
In the early 1800's George Scott Esq. is listed at Annaclare. He seems to have held high status in the Armagh community and church. He had no children and when he died in 1857 passed Annaclare to his nephew and namesake, George Scott. When he died intestate in 1864 it went to his father Thomas of Salter's Grange (brother of George Esq.) On his death in 1865 he bequeathed it to his eldest daughter, Mary Ann, but with his son, John Scott, as sole executor. John seems to have been in possession around the time of his marriage to Eliza Newton about 1872. They had five children, that I can account for, when he died. She married Henry blending his three or four children with hers.
Also to add that the daughter of John and Elizabeth Scott, Elizabeth Adelaide Scott did marry Herbert Couser.
I hope this helps. I'd love to know more myself. I'm too far away to make local inquiries
