Knox (Castlereagh)

The Knoxes came from county Donegal and settled at Castlereagh in the 17th century. By the early 19th century they held an extensive estate of more than 10,000 acres in the barony of Gallen, county Mayo, situated mainly in the parishes of Templemore, Kilconduff and Killedan. They also owned most of the parish of Doonfeeny, in the barony of Tirawley and land in the parish of Kilmeena, barony of Burrishoole. In 1835 Arthur Edward Knox married Jane, daughter of the 2nd Earl of Rosse of Birr Castle. In 1853 Arthur E. Knox sold his estates in the Encumbered Estates' Court. The first sale amounted to 16,178 acres in three county Mayo baronies Gallen, Burrishoole and Costello and in the barony of Coolavin, county Sligo and the second sale comprised 25,004 acres in the barony of Tirawley and 1059 acres in the barony of Gallen. He and his wife went to live at Trotton House in Sussex. Their eldest son, Laurence E. Knox, founded the ''Irish Times'' newspaper in 1859. In the 1870s the representatives of Laurence E. Knox, Dublin, owned 902 acres in county Tipperary.
