On 19 January 1586 Queen Elizabeth I of England granted a pardon (No. 4813) to Manus Oge M'Manus M'Thomas Magawran of Coor for fighting against the Queen's forces. The said Manus Og McGovern was the grandson of Tomas Mág Samhradháin who was chief of the McGovern Clan from 1512 to 1532. His son Hugh was granted land in Crossmakelagher and Bofealan in 1611 under the Plantation of Ulster.
In the Plantation of Ulster by grant dated 26 June 1615, King James VI and I granted, inter alia, two polls in Cor to Sir George Graeme and Sir Richard Graeme to form part of the Manor of Greame. An Inquisition held at Cavan Town on 31st October 1627 found that George Greames was seized of one poll in Corr and he died 9 October 1624. By his will dated 1 May 1615 he left his lands to his son and heir William Greames then 30 years old (born 1594) and unmarried. After the Cromwellian Act for the Settlement of Ireland 1652 the Graham family were still in possession of Cor.
