  Marriage Notes:

"Isabel, a daughter who, according to Barbour, married Edward Bruce, Earl of Carrick, and brother of King Robert Bruce. She had a son Alexander who was killed at Halidon in 1333. Various grants were made by King Robert to this lady, styled Isabel de Atholia, and to his nephew Alexander. Barbour states that Edward Bruce's coldness to his wife was the cause of a quarrel with her brother. She apparently died before June 1317, when Edward Bruce had a dispensation to marry Isabel Ross."

from Scots Peerage (vol 1)




"On 1 June 1317 a dispensation was granted by Pope John XXII. permitting the Earl of Carrick to marry Isabella, daughter of William Earl of Ross, notwithstanding their being within the third and fourth degrees of consanguinity, but it is doubtful if the marriage actually took place. He had a son Alexander by Isabel of Atholl, sister of David de Strathbogie, Earl of Atholl, his relations with whom caused a quarrel between the two earls. He is generally said to have left three illegitimate sons, Robert, Alexander, and Thomas, who successively became Earls of Carrick, but this is a mistake. Robert never existed, or has been confounded with a son of King Robert of that name ; Alexander did become Earl of Carrick, as will be mentioned hereafter, but Thomas never held the title, while it is not certain that he was a son of Edward, though there can be no reasonable doubt that he was the progenitor of the Bruces of Clackmannan."

"Alexander de Brus was a son of Edward, Earl of Carrick, by Isabel, sister of David, Earl of Atholl, though he cannot have been legitimate, otherwise he would have succeeded to the earldom on his father's death."
