A census in 1659 recorded only three people, or perhaps three households.
According to Patrick Heraughty, Inishmurray was in the modern era owned by the Hipsley and Sullivan estate. These owners had someone approach farmer Domhnall O'Heraughty with the proposition that in exchange for his holdings elsewhere he take the whole of Inishmurray to farm. "Domhnall was not a ready taker and tried to parry the offer as best he could, but both men knew that as a tenant Domhnall was in the weaker position. One of Domhnall's objections was that he would not be able to find a wife to live in isolation with him on the island. But the adroit Wynne was prepared for this, and had obtained the agreement of Margaret McNulty, a cook at Hazelwood, that she would marry Domhnall and go to the island with him. With this and some minor objections overcome, Domhnall had little choice but to accept the offer of Inishmurray." (Heraughty, Patrick. Inishmurray: Ancient Monastic Island.
