In the Plantation of Ulster by grant dated 26 June 1615, King James VI and I granted, inter alia, one poll in Gortnefreighan to Sir George Graeme and Sir Richard Graeme to form part of the Manor of Greame. An Inquisition held at Cavan Town on 31 October 1627 found that George Greames was seized of one poll in Gortnafreighane 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 Gosnefrehane.
