History
In medieval times Porturlan stretched northward up to Templeport Lough and included the modern townland of Ray, together with other subdivisions called Killcroghan and Alico. The 1609 Baronial Map depicts the townland as Kilcrooghan. The 1652 Commonwealth Survey lists it as Killecrooghan. The 1665 Down Survey map depicts it as Killerachan. William Petty's 1685 map depicts it as Killracan. In the Plantation of Ulster by grant dated 29 April 1611, along with other lands, King James VI and I granted the two polls of Killcroghan and one poll of Porturilinchy to the McGovern Chief, Feidhlimidh Mág Samhradháin. The townland had been part of the McGovern chief's personal demesne for several hundred years before this and it was just a Surrender and regrant confirming the existing title to the then chief. This is confirmed in a visitation by George Carew, 1st Earl of Totnes in autumn 1611 when he states that Magauran had his own land given him on this division. An Inquisition of King Charles I of England held in Cavan town on 4 October 1626 stated that the aforesaid Phelim Magawrane died on 20 January 1622 and his lands, including two polls of Kilcroghan and one poll of Portnerilinchy, went to his son, the McGovern chief Brian Magauran, who was aged 30 and married. The McGovern lands in Porturlan were confiscated in the Cromwellian Act for the Settlement of Ireland 1652 and were distributed as follows- The 1652 Commonwealth Survey lists the proprietor of Killecrooghan as John Boyd. In the Hearth Money Rolls compiled on 29 September 1663 there were two people paying the Hearth Tax in Killecrohean- John Bride and Robert Grige. A grant dated 30 January 1668 was made from King Charles II of England to Mary Boyd for the 34 acres and 6 perches in the parts of ye cartron of Kilcrohan at an annual rent of nine shillings and twopence farthing. A grant dated 30 January 1668 was made from King Charles II of England to William Chambers for 20 acres 2 roods and 27 perches in Porturlan alias Killcroghan at an annual rent of fourteen shillings and sixpence. A grant dated 9 September 1669 was made from King Charles II of England to Arthur Annesley, 1st Earl of Anglesey, for 27 acres in the south part of Killerachan at an annual rent of seven shillings and threepence halfpenny and for 17 acres and 3 perches in the northwest part of Killerachan at an annual rent of four shillings and seven pence. The 1790 Cavan Carvaghs list spells the name as Porturlin. The Tithe Applotment Books for 1827 list seven tithepayers in the townland. In the early 1800s a Sunday school was kept in the townland, funded by the Hibernian Sunday School Society. In June 1819 it had an attendance of 100 scholars. The Porturlan Valuation Office Field books are available for 1839-1840. A rental with a list of tenants of the Thornton estate in Porturlan dated 1843 is held in The County Cavan Archives. Griffith's Valuation of 1857 lists five landholders in the townland.
