Note 490 — Chapter XIII · WILLIAM THE LION—1165–1214.

Trivet 1209, and the Bridlington Chronicle (in Documents, etc., relating to Hist. Scot., No. xxi., sec. 26, p. 66) state that William was going to marry one of his daughters to the Count of Boulogne. Hemingburgh, vol. 1, p. 242, affirms that the princess was to have been united to the Count of Flanders. Ida, who brought the earldom of Boulogne to her husband, Reginald de Dammartin, and whose heiress, Mahout, was married to Prince Philip of France, was married about 1191, and survived till 1216. There was no Count of Flanders in 1209. Baldwin of Hainault, who ascended the imperial throne of Constantinople in 1204, and was slain in the following year, left by Margaret his wife, who brought him the earldom of Flanders, two daughters, who became the wards of Philip Augustus. By that king the eldest, Jane, was given to Ferrand of Portugal in 1211, who in her right became Count of Flanders and Hainault. It is very clear, then, that William could not have been negotiating a marriage for one of his daughters with either a Count of Boulogne, or of Flanders, at that period; and if any negotiation on such a subject had been set on foot, it must have been respecting an alliance between the prince of Scotland and the heiress of Flanders and Hainault. Such a project would have suited well with the endeavours of Philip to enlist allies against John, and it would undoubtedly have brought the latter king in all haste to the northern frontier.
