John Eyre, an Englishman who was granted a large parcel of land in recognition of his part in the military campaign in Galway during the Cromwellian conquest of Ireland.
[1] A 7-bay two-storey house "built on a symmetrical pattern with a central staircase and hall taking up nearly a third of the overall space, it was an impressive, modern residence for the new landowner".
A visitor in 1731, Mary Granville, commented on a "great many fine woods and improvements that looked very English" in the parkland around the house.
[7] In 1662 Colonel John Eyre was granted the 800 acres (320 ha) of Eyrecourt land, with the power to empark it, as reward for his role in Cromwell's Irish campaign.

William Randolph Hearst bought the ornately carved staircase of Eyrecourt Castle in 1927 and had it shipped to the United States.
