Four of the competitors, John Baliol, Robert Bruce, John Comyn, and William Ross, are all barons of England as well as of Scotland, and their lands lying in the north they were, of course, included in the invitation.

In May, Edward issued an invitation to the Bishops of St.Andrews, Glasgow, and other Scotch nobles to come to Norham, remain there, and return, specially saying that their presence there was not to be regarded as a custom through which the laws of Scotland might in any future time be prejudiced.

Hither then came the whole power of the north of England, and many of the Scotch nobles.
"When the court opened, Roger Brabazon, the king's justiciary, delivered an address, in which he stated that Edward, as lord paramount of Scotland, had come there to administer justice between the competitors for the crown, and concluded with the request that all present should acknowledge his claim as lord paramount.

The Scottish nobles present, with the exception of those who were privy to Edward's designs, were filled with astonishment and dismay at this pretension, and declared their ignorance of any claim of superiority of the King of England over Scotland.

The king, in a passion, exclaimed: "'By holy Edward, whose crown I wear, I will vindicate my just rights, or perish in the attempt.' "However, he saw that nothing could be done on the instant, and adjourned the meeting for three weeks, at the end of which time the prelates, nobles, and community of Scotland were invited to bring forward whatever they could in opposition to his claim to supremacy.
"At the time fixed the Scotch nobles again met, but this time on the Scottish side of the Border, for Edward had gathered together the whole of the force of the northern counties.
"Besides the four claimants, whose names I have told you, were Sir John Hastings, Patrick Dunbar, Earl of March, William de Vesci, Robert de Pinkeny, Nicholas de Soulis, Patrick Galythly, Roger de Mandeville, Florence, Count of Holland, and Eric, King of Norway.
With the exception of Eric, the Count of Holland, Dunbar, and Galythly, all of these were of Norman extraction, and held possessions in England.
