In the Plantation of Ulster by grant dated 27 February 1610, along with other lands, King James VI and I granted one poll of Tawnihulch containing 50 acres at an annual rent of £0-10s-8d to Cahill McBrien O'Reily, gentleman.
Cathal O'Reilly then sold the land to Walter Talbot of Ballyconnell.
An Inquisition held at Cavan Town on 14 March 1630 found that Walter Talbot died on 26 June 1625 at Ballyconnell and his son James Talbot succeeded to, inter alia, one poll in Tonenelwlagh, aged just 10 years. James Talbot married Helen Calvert, the daughter of George Calvert, 1st Baron Baltimore of Maryland, USA, in 1635 and had a son Colonel George Talbot who owned an estate in Cecil County, Maryland which he named Ballyconnell in honour of his native town in Cavan. George Talbot was appointed Surveyor-General of Maryland in 1683. In the aftermath of the Irish Rebellion of 1641 James Talbot's estate in Tonyhallagh 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.
In the Cromwellian Act for the Settlement of Ireland 1652 Talbot's lands in Tonyhallagh were distributed as follows-
The 1652 Commonwealth Survey lists the proprietor as being Lieutenant John Blackforde and the tenant as Gilleesaog O'Rely, who also appear as proprietor and tenant for several other Templeport townlands. In the same survey Blackforde is also listed as the proprietor of Rosstawny. John Blachford was born in 1598 in Ashmore, Dorset, England, the son of Richard and Frances Blachford. He became a merchant in Dorchester, Dorset but fled to France in 1633 when facing a warrant from the Exchequer for not paying customs. He married Mary Renald from Devon and died at Lissanover, County Cavan in 1661 and was buried at St. Orvins in Dublin despite wishing to be buried back in Dorchester. His will was published on 9 January 1665 leaving his son John Blachford as his sole heir. An Inquisition held in Cavan on 21 May 1667 found that his widow Mary Blachford and his heir John were seized of, inter alia, the land of Tonyhallagh alias Townehuck. He had sons John, Thomas, Ambrose and William (who became a Major) and daughters Mary and Frances. Major William Blachford was born in 1658 and died at Lissanover on 28 March 1727. The Blachford family gravestones in Templeport Church read as follows- This monument was erected by MAJOR WILLIAM / BLASHFORD of Lisnover in 1721 to the memory of / his father, JOHN BLASHFORD, late of the same Esqr. but / from Dorchester in Dorsetshire, the place of his / nativity, who in his lifetime chose this for a burying / place, for himself and family, but died in Dublin / was buried in St. Orvins Church but his wife, MARY / RENALD of a Devonsheire family is buried here / as also three sons and two daughters, viz JOHN / AMBROSE AND THOMAS; MARY AND FRANCES / Here likewise lies buried two wives of MAJOR WILLIAM BLASHFORD, son to the said JOHN BLASHFORD viz / MARY MAGHEE of an ancient Family in Lincolnsheire.
