"William le Latimer, who, in the 38th of Henry III., was made sheriff of Yorkshire, and governor of the castle at York, and the next year governor of Pickering Castle. In his sheriffalty he continued for nearly five years, during which period he had a military summons to march into Scotland in aid of (the minor) King Alexander, (Henry III's son-in-law) against his rebellious subjects, and he was constituted escheator-general throughout all the counties of England. In the 47th Henry III., he obtained the king's precept to the conservators of the peace, in the counties of York, Cumberland, Northumberland, Lincoln and Northampton, to make restitution to him of all his lands which had been seized in the baronial war. He appears, however, in those contests to have sided with the crown, for we find him upon the full re-establishment of the power of the king, again filling the office of sheriff of Yorkshire, and again governor of the castles at York and Scoarborough. He also received a compensation of one hundred marks for the expenses he had incurred. In the 54th of Henry III., he was, amongst others, signed with the crown, to accompany Prince Edward to the Holy Land. In the 10th of Edward I., he was in an expedition against the Welsh, and in several years after he accompanied the famous soldier, John St. John, in an expedition in Gascony. From this period he seems to have been almost uninterruptedly employed in the wars in Scotland and Gascony, and for his services was summoned to parliament as a Baron, from the 29th December, 1299, to 22nd January, 1305. He obtained about the same time, a grant from the crown, of the manor of Danby, in the county of York. His Lordship m. Alice, daugher and co-heir of Walter Ledet, by whom he acquired a moiety of the Barony oF Warden, in the county of Northampton, and a moiety of the town and whole hundred of Corby, in the same shire."
