What these “matters” were is nowhere stated. Later indications, however, point to a probability that all these obscure proceedings resulted in a ratification of the treaty as a whole, but with a modification of one article. William the Lion had given the wardship and marriage of his two daughters, Margaret and Isabel, to John, with fifteen thousand marks which were, seemingly, intended to form their dowries. The only copy of the treaty of Norham which we possess says nothing more on the subject than this; but from other sources we have reason to infer the existence in the original text of a further stipulation, that the elder girl, Margaret, was to become the wife of John’s heir, or if the boy should not live long enough, of the next heir, the baby Richard; and also of a formal surrender, made on the express condition of this marriage, of all the Scot King’s claims upon Northumberland, Cumberland, and Westmorland.[601] When this treaty was made, in August 1209, Henry’s age was one year and ten months; Richard’s was seven months. Margaret of Scotland was fourteen years old at the least.[602] By 1218 Margaret’s brother and Henry’s guardians must all alike have begun to feel that this clause as it stood was doomed to prove impracticable. Henry’s great-grandfather Geoffrey of Anjou had, indeed, at the age of fifteen, married a woman ten years older than himself; and the difference of age between Henry II and Eleanor was probably not much less. But Eleanor was Duchess of Aquitaine, and Geoffrey’s bride was heiress of Normandy and England; while Margaret could bring to her husband nothing beyond her share of the fifteen thousand marks. The guardians of the reigning King of England might fairly expect to have no difficulty in finding for him in due time a matrimonial alliance fraught with greater advantages, personal and political, than were offered by a marriage under these circumstances with a sister of his own vassal; and Henry himself, when old enough to decide, was almost certain to repudiate the engagement so lightly made for him by his father. On the other hand, unless some steps were taken in anticipation of this contingency, Scotland might find that she had given England fifteen thousand marks for nothing: the non-fulfilment of this unlucky clause would invalidate the whole treaty, and might lead to a rupture between the two countries, which both parties desired to avoid. After Henry’s final coming of age in 1227, we are told, he had to give the King of Scots two hundred pounds worth of land for the quit-claim of the three northern counties, “because the former agreements[603] were not observed”--that is, because Henry had not married Margaret.[604] This compensation for his failure to marry her may have been agreed upon between the two Kings when she was betrothed to Hubert de Burgh in 1220 or 1221. Possibly, however, and even more probably, it may have been settled in Pandulf’s presence in November, 1219.
