This family of Knoxes also owned 5434 acres in county Sligo. The Knox family estate in the parish of Achonry was derived from a grant of land to Jeremy Jones at the Restoration. At the time of Griffith's Valuation, Reverend George Knox and Frederick Knox were lessors of townlands in the parish of Achonry, barony of Leyny. In the 1870s they owned over 800 acres in county Sligo. At the same time Utred Knox of Mountfalcon, Ballina, owned over 3500 acres in county Sligo. By March 1916 Utred A. Knox had accepted a final offer from the Congested Districts' Board for the purchase of his estate. This included over 1600 acres acquired by the Board in county Sligo, principally in the barony of Leyny. In 1916 Hercules and Reginald Knox accepted offers from the Board on 1900 and 900 acres respectively. .
