Sir Hugh Eglintoun of that Ilk, who was Justiciary of Lothian, Anno 1361b 1.2. He married Giles, Daugh|ter of Walter Lord high Stewart of Scotland, Sister to King Robert II, upon whose Advancement to the Throne, he obtained diverse Grants of Lands, and several Imployments, but leaving no Male Issue, his Estate went to his Daughter and Heir, mar|ried to Sir John de Montgomery of Eglesham, Knight, whose Ancestor
