- The O'Donnell family leased the Larkfield property from the Lane-Fox estate. According to O Duigneain, Hugh O'Donnell (1691-1754) was the first O'Donnell to settle at Larkfield. The O'Donnells married into the Phibbs of Branchfield, county Sligo and the Montgomery family of Belhavel, county Leitrim. They also acquired the Greyfield estate near Keadue, county Roscommon. The estate at Larkfield was eventually purchased by the Land Commission in the 1930s.
