AVERHAM, (Nottinghamshire) on the W. side of the Trent, bet. Southwell and Newark, was, soon after the conquest, the estate of the Tysens, from whose family, by the marriage of a daughter, it passed to that of the Hesets. From their heirs it passed to Robert Sauvage, who granted it to Robert de Lexington, the ancestor of John, Ld. Lexington, in the R. of Hen. III. from whom, by marriage of a sister, it came to the Suttons, since created Lds. Lexington; but now it is a seat of the D. of Rutland. The Trent divides at a place in this p. called Upper Wear, and rejoins at another, called Crankleys, in the p. of S. Mulkam.
