Landed Estates
NUI Galway


The Hillas family held property in several parishes in the Barony of Tireragh. They also held property in the City of Dublin. The family held over 7000 acres in County Sligo in 1876. According to documents in Sligo County Library the Hillas family initially rented and later purchased lands formerly owned by the D'Arcy family of Kiltulla, county Galway. The Hillas family were also connected to the Fenton families of Dromore and Easky. A duel was fought between John Fenton and Major Hillas over the rights to a shipwreak during which Major Hillas was killed. Bateman records that R. Hillas of Seaview was the owner of 7771 acres in county Sligo in the 1880s. In 1906 Robert G. Hillas is recorded as the occupier of property at Carrowmacrory townland, barony of Tireragh, including a mansion house.
