Landed Estates
NUI Galway


In the late 17th century a junior branch of the Newcomen family of county Longford moved to Knock, county Roscommon. Knock was among the 9,000 acres + in counties Roscommon, Galway, Sligo and Mayo granted to Sir Thomas Newcomen in July 1677 and November 1678. The Newcomens were residing at Camlagh by the 1740s which was soon after leased to the Keoghs. The county Galway part of the Newcomen estate was in the parish of Annaghdown, barony of Clare but the main part of their estate was in the county Roscommon parishes of Taghmaconnell, barony of Athlone and Kilbride and Roscommon, barony of Ballintober South. In the 1870s two George Newcomens are recorded, one a minor and ward of the Court of Chancery, the other with an address in county Meath. Each owned an estate of over 2,200 acres in county Roscommon. Over 850 acres belonging to George A. Newcomen in county Galway were vested in the Congested Districts' Board on 31 March 1914. John Newcoman owned 574 acres in county Galway in the 1870s.
