Mullaghmore, historically known as Moyloughmore and later as Perrymount, formed the principal seat of the Perry family in County Tyrone. The estate represents the earliest established centre of the Perry family’s presence in the parish of Clogherny and the Barony of Omagh.
The house at Mullaghmore, later known as Perrymount, served as the focal point of a substantial estate which would ultimately pass, through inheritance, into the hands of the McClintock family of Newtown, County Louth.

The Perry family, said to be of Welsh origin, became established in the area in the mid-seventeenth century. Thomas Perry (d. c.1662) is the earliest identifiable ancestor associated with the locality.
On 20 June 1662, Sir William Usher conveyed the lands of Ranelly to James Perry, son of Thomas Perry. Shortly thereafter, on 26 June 1662, Sir Audley Mervyn granted a fee farm of the lands of Moyloughmore, Mullorkmore or Mullaghmore to the same James Perry.
These transactions mark the foundation of the Perry estate in the district.
—
James Perry established his residence at Moyloughmore, naming it Perrymount. The estate became the principal seat of the family and remained associated with them throughout the eighteenth century.
—
The eventual transfer of the estate to the McClintock family arose through the marriage of Mary Perry, daughter of Samuel Perry of Perrymount, to Alexander McClintock of Newtown, County Louth, in December 1781.
Subsequent inheritance arrangements, particularly under the will of George Perry (d. 1824), directed that the estate should pass through this line.
