The history of the Mullaghmore and Seskinore estates is shaped by a closely connected network of families whose marriages and relationships influenced inheritance, landholding, and social position.
Rather than existing as separate lines, these families formed an interconnected structure centred on the Perry and McClintock estates.
CORE ESTATE FAMILIES
• Perry Family of Perrymount (Mullaghmore)
• McClintock Family of Seskinore and Newtown
The Perry family established the estate in the seventeenth century. Through the marriage of Mary Perry to Alexander McClintock in 1781, the estate passed into the McClintock family.
PRIMARY MARRIAGE CONNECTIONS
The Lowry family became connected through multiple marriages:
• Catherine Lowry married Samuel Perry
• Elizabeth Lowry married Francis Perry
This represents one of the earliest and strongest connections into the Perry line.
• Angel Sinclair married George Perry (c.1700–1774)
This marriage connects the Perry family to clerical and landed networks in the wider region.
• A daughter of the Olphert family married Samuel Perry (b. c.1730)
This alliance links the Perrys to Donegal landed families.
• Mary Burgess married George Perry (1762–1824)
This connection explains George Perry’s residence in Armagh and links the estate to Parkanaur.

Eccles Family of Ecclesville
• Amy Henrietta Eccles married Colonel John Knox McClintock
• Their daughter, Amelia (Leila) Isobel Eccles McClintock, became heiress of Seskinore
This connection links the Ecclesville estate to the later history of Seskinore and the transfer of ownership into the Joynson–Wreford family.
McCLINTOCK CONNECTION
• Mary Perry married Alexander McClintock (1781)
This is the key transfer point where the estate passed from the Perry family into the McClintock family.
• Samuel McClintock married Dorothea Knox
This represents the continuation of alliance-building after the estate had passed into McClintock ownership.
NETWORK SUMMARY
The estate history can therefore be understood as:
Perry (foundation)
↓
Lowry / Sinclair / Olphert (marriage network)
↓
Burgess (Armagh connection)
↓
McClintock (inheritance through Mary Perry)
↓
Knox (later alliance)
This interconnected structure demonstrates how estate ownership, residence, and influence passed not only through direct inheritance, but through a carefully developed network of family alliances.
