Landed Estates
NUI Galway


A family originally from Munster who purchased land in the barony of Erris, county Mayo, in the early 17th century. One of their main strongholds was the castle at Inver. Some deeds in the Westport Papers document their activities in 17th century county Mayo, including their purchase of a large estate in the barony of Erris, from the Brownes in 1700. The Cormacks were also the head tenant of more than 30,000 acres in the barony of Tirawley which was mortgaged by the Brownes to Richard Thompson and included more than 28,000 acres known as the Commons of Crossmolina. By the 18th century the Cormacks were residing at Castlehill and Mullinmore in the parish of Crossmolina, barony of Tirawley. Captain Michael Cormick is listed as an absentee proprietor for the barony of Burrishoole in the Statistical Survey of 1802. Major Michael Cormack of Castlehill died in 1835 and his property passed to his two sisters, who were married to Edmond Coyne of Farmhill, county Roscommon, and John Walsh of Hume St, Dublin. Walsh had Castlehill and added the name Cormack to his surname.
