Adam De Heaton

"In 1278 Adam son of Richard de Heaton was non-suited in a claim for common of pasture brought against Ellis son of Randle de Heaton; ibid. 1238, m. 31 d. Ellis de Heaton appears as plaintiff in 1292, alleging that Randle his father was disseised of two parts of 4 acres of wood and 3 acres of pasture in Heaton by one Roger de Pendlebury, who demised them to William de Pendlebury, from whom they appear to have been acquired by Richard son of David de Hulton; ibid. 408, m. 49. He made a similar claim against Hugh de Halliwell (ibid.), but failed in both cases. In 1301 John son of Ellis de Heaton was defendant in a claim made by John del Shaw for reasonable estovers in Heaton, without view of the foresters, for housebote and heybote; ibid. 1321, m. 9 d. According to the surveys of 1320 and 1322 John de Heaton owed homage and fealty for the tenth part of a fee in Heaton under the Forest, and rendered yearly for sake fee 8d. and for ward of Lancaster Castle 12d., and puture of the serjeants and foresters; Mamecestre, 288, 379. At that time four oxgangs in Heaton contributed proportionally to the maintenance of the foresters of Horwich; ibid. 376, 377."
