This charter is dated mainly on the ground of Henry of Braid, sheriff of Edinburgh. This seems to come after Henry of Graham’s tenure as sheriff, which was sometime around 1189×95, and Henry witnesses this charter. Henry of Braid also witnesses a charter dating to 1199×1212 (<em>Holyrood Liber</em>, no. 33, which is dated based on John of Leicester as archdeacon of Lothian). The charter is also witnessed by Master Stephen, <em>persona</em> of Borthwick, who witnessed many charters between 1200 and about 1220. For reasons unknown, Watt dates this charter 1165 × 1199 (<em>Graduates</em>, 342). This charter must have come after the royal confirmation of David of Lyne’s grant (_RRS_ ii, no. 191).
