Surnames of old families in Angus, derived from the lands of Auchterlonie near Forfar. John of Othirlony exchanged with Walter, son of Turpin his lands of Othirlony for those of Kenny c. 1226—39 (RAA., I, p. 262—263). Wauter de Oghterloveny of the county of Fyfe who rendered homage in 1296 (Bain, II, p. 209) is said in Nisbet to be Auchterlonie of that Ilk. William of Ochterlowny was one of the assize on the marches of Woodwrae in 1388 (Bamff, p. 22). Alexander de Uchtirlowny was a charter witness in Perth in 1410 (RMS., I, 927), Thomas de Ochtirlony a charter witness in Dundee in 1430 (HP., II, p. 164), and David Ochterlovnie witnessed an instrument of the procurator of Brechin in 1457 (REB., II, 140).
