Landed Estates
NUI Galway


An estate of over 3,000 acres in the baronies of Clonmacnowen and Kilconnell, county Galway, was granted to John Donnellan by patent dated 6 Feb 1677/8. Burke states that the Donnellan families of Ballydonnellan, Nutgrove and Hillswood derive from him while the Donnellans of Ballyeighter descend from his younger brother, Richard. Anthony Donnellan, Ballyeighter and Stephen Donnelan, Killagh, are recorded as resident proprietors in 1824. The Ballydonnellan estate, the property of Charlotte Donelan, was offered for sale in the Encumbered Estates court in July 1850. In the 1870s the Donnellan estate at Killagh amounted to over 1100 acres. For more information on the Donnellan estate see
