Mahon/Pakenham-Mahon

In February 1666 Captain Nicholas Mahon was granted over 2,700 acres in the barony of Roscommon and in July 1678 he was granted over 3,000 acres in the baronies of Roscommon and Ballintober county Roscommon. The latter became the Manor of Ballynamully or Strokestown, 500 acres to be held as demesne. Thomas Mahon represented the borough of Roscommon 1739-1763 and the county from 1763-1782. His son and heir, Maurice Mahon, was created Baron Hartland of Strokestown in July 1800. The Honourable S. Mahon was a member of the Grand Panel of county Roscommon in 1828. The title died out with the death in 1845 of Maurice, 3rd Baron Hartland. He was succeeded by his cousin, Major Denis Mahon, who was murdered in 1847. Grace Catherine Mahon, the heiress, married Henry Sandford Pakenham, eldest son of the Honourable and Reverend Henry Pakenham and they took the additional name of Mahon. Their only son Henry had one child, a daughter Olive. The Ordnance Survey Name Books record Thomas Conry as agent to Lord Hartland. In the 1850s Henry Sandford Pakenham-Mahon held land in the county Roscommon parishes of Dysart, barony of Athlone, Kilglass and Kilmore, barony of Ballintober North, Kilbride, Kilgefin, barony of Ballintober South, Cloonfinlough, Bumlin, Aughrim, Elphin, Kilbride, Kiltrustan, Lissonuffy, barony of Roscommon. In the 1870s the Pakenham Mahon estate amounted to almost 27,000 acres in county Roscommon. Over 8,600 acres of the Mahon estate was vested in the Congested Districts' Board in March 1911 and July 1912. The Strokestown House archive is now located at the OPW-NUI Maynooth Archive and Research Centre at Castletown, county Kildare.
