The Plantation of Ulster 1609 Baronial Map depicts the townland as Nahowen. A 1610 grant spells it as Nahownee. A 1630 Inquisition spells it as Nationna. The 1652 Commonwealth Survey lists the townland Lehcharrownehowen. A 1660 grant spells it as Lacaranehane, alias Nahone, alias Lackanehone. The 1665 Down Survey map depicts it as Lackaneaghone. William Petty's map of 1685 depicts it as Lakanhon. In the Plantation of Ulster by grant dated 23 June 1610, along with other lands forming the Manor of Calva, King James VI and I granted two polls of Nahownee to Hugh Culme. In the same year Culme surrendered his interest to Walter Talbot of Ballyconnell. Walter Talbot died on 26 June 1625 at Ballyconnell and his son James Talbot succeeded to the Ballyconnell estate aged just 10 years. An Inquisition held in Cavan on 20 September 1630 found that James Talbot was seized of two polls of Nationna, along with other lands. James Talbot married Helen Calvert, the daughter of George Calvert, 1st Baron Baltimore of Maryland, USA, in 1635. In the aftermath of the Irish Rebellion of 1641 James Talbot's estate was confiscated because he was a Catholic and he was granted an estate in 1655 at Castle Rubey, County Roscommon instead. He died in 1687. Talbot's land in Lecharrownahone was distributed as follows- The 1652 Commonwealth Survey lists the townland as belonging to Captain Gwilliams and the tenants as Edward Rely & Others. In the Hearth Money Rolls compiled on 29 September 1663 there were four Hearth Tax payers in Lecarrownehawna- Brian O Relly, Teige O Clery, William McMurphy and Owen McMurphy. A further confirming grant dated 11 August 1666 was made from King Charles II of England to Thomas Guyllym of Ballyconnell including 200 acres 3 roods and 8 perches in Lacaranehane, alias Nahone, alias Lackanehone. The Gwyllym estate was sold for £8,000 in 1724 to Colonel Alexander Montgomery of Convoy House, County Donegal, M.P. for Donegal Borough 1725 to 1727 & for Donegal County 1727 to 1729. He died in 1729 and left the Ballyconnell estate to his nephew George Leslie who then assumed the name George Leslie Montgomery. George Leslie Montgomery was M.P. for Strabane, County Tyrone from 1765 to 1768 and for County Cavan from 1770 to 1787, when he died and left the Ballyconnell estate to his son George Montgomery, whose estate was administered by the Court of Chancery as he was a lunatic. George Montgomery died in 1841 and his estate went to his Enery cousins of Bawnboy. In 1856 they sold the estate to take advantage of its increased value owing to the opening of the Woodford Canal through the town in the same year. The estate, including Lecharrownahone, was split up among different purchasers and maps & details of previous leases of the sold parts are still available. In the Templeport Poll Book of 1761 there were only three people registered to vote in Lecarnahone in the 1761 Irish general election - William Chambers, Simon Fisher and William Taylor. They were entitled to two votes each. All three voted for Charles Coote, 1st Earl of Bellomont who was elected Member of Parliament for Cavan County and for George Montgomery of Ballyconnell, who lost the election. It was no surprise they voted for Montgomery as he was their landlord. Absence from the poll book either meant a resident did not vote or more likely was not a freeholder entitled to vote, which would mean most of the inhabitants of Lecharrownahone. The 1790 Cavan Carvaghs list spells the name as Leearunehone. The Tithe Applotment Books for 1827 list twenty six tithepayers in the townland. The Lecharrownahone Valuation Office Field books are available for 1840-1841. Griffith's Valuation of 1857 lists thirty six landholders in the townland.
