Robert Lecky, born in 1649, was the first of many generations to reside at Ballykealey, establishing a lineage that spanned over three centuries and witnessed significant events in Irish history.

At its peak, the Lecky estate comprised nearly 1,500 acres of fertile land around Ballon village. Although smaller compared to other estates in the region, Ballykealey House reflected the prominence of its owners. The house was transformed from a large farmhouse into the magnificent Tudor Revival mansion we see today in 1830, designed by the eminent architect Thomas A. Cobden, who also designed Carlow Cathedral and Dublin’s Custom House.

John James Lecky upon his marriage to Sarah Lucia Smith 1825, played a crucial role in the construction of the new Ballykealey House. The best tradesmen, including Italian stucco plaster workers and marble specialists from Carrara, were employed to create its intricate interiors and ornate fireplaces. The surrounding grounds were designed by Scottish landscaper Gregg, whose work is still evident today.

The Lecky family were known for their moderate and kind approach to landlordism, especially during the Great Famine when they provided a soup kitchen and supplied oatmeal to the locals. This generosity was influenced by their Quaker beliefs, emphasizing concern and help for the poor. Similar to their Watson relations at Altamont, the Leckys also created an impressive lake to provide employment for locals during hard times.
