Alan la Zouche or ZOUCH, ALAN la or de la, Baron Zouche (d. 1270), was the son of Roger de la Zouch and the grandson of Alan de la Zouch. This elder Alan, the first of the family to be established in England, was a younger son of ‘Galfridus vicecomes,’ that is, in all probability of Geoffrey, viscount of Porhoet in Brittany (d. 1141); his elder brother, Eudes de Porhoet, was for a few years count of Brittany, but with a disputed title, and his uncle, also named Alan, was founder of the viscounty of Rohan (cf. A. de la Borderie, Géographie féodale de la Bretagne, p. 29). Under Henry II Alan de Porhoet, or de la Zouch, established himself in England, and married Adeliza or Alice de Belmeis, sole heiress of the house of Belmeis , her inheritance including Tong Castle in Shropshire, Ashby (afterwards called Ashby-de-la-Zouch) in Leicestershire, North Molton in Devonshire, and other lands in Cambridgeshire and elsewhere. As her husband, Alan de la Zouch became an important personage at Henry II's court. Their sons, William de la Zouch (d. 1199) and Roger de la Zouch (d. 1238?), succeeded in turn to these estates. Roger's Breton connection was almost fatal to him in 1204 (Rotuli Normanniæ, pp. 130, 139), but he managed to regain John's favour, and devoted himself to that king to the last. In the first year of Henry III's reign he was rewarded by receiving grants of the forfeited estates of his kinsmen, the viscounts of Rohan (Rot. Lit. Claus. i. 366, 385, 423). He died before 3 Nov. 1238 (Excerpta e Rot. Fin. i. 315).
