Somebody kindly sent this on to me for the reason that the Grays in the Orr Pedigree lived in Ballyvernet which is on the Clandeboye Estate and adjacent to Conlig:
The House is sometimes called "Little Clandeboye" and I have heard or read that it was (or was intended to be) a dower house..
Ros Davies has the following to say about it
Large house in Conlig townland with gate lodge .Residence of William Pirrie in 1852.; unoccupied in 1863 but owned by Lord Dufferin & Clandeboye.Rresidence of James Barratt in 1902.
