Her legitimacy was brought into question by Sir David Dalrymple in his work The Annals of Scotland volume 2. Sir David Dalrymple first read about Elizabeth Bruce in Crawford's Peerage. Because he had never heard of her before, he questioned her existence. There is no evidence to substantiate the illegitimacy and it was based upon two points. Firstly, that Elizabeth is not mentioned by Fordun or his successors and secondly that Sir David Dalrymple had not seen any of the charters in which Elizabeth was named. Dalrymple concludes that "To remove all doubt" the charter with the words "dilectae sorori nostrae" if still in existence, should be deposited in Register House. There are many royal charters signed by King David II, in which she is described as "dilecte sorori me" - "my beloved sister". and "dilecte sorori nostre" - "our beloved sister". which thus remove that doubt. In all, there are similar charters for the lands and baronies of Gask, Dupplin, Ochtertyre, Newtyle, Kynprony, Turyngs and Dromy. The reason for the existence of so many charters was that Sir Walter Olifaunt and Elizabeth Bruce his wife had obtained reconfirmation of their landholdings and baronies from her brother King David ii in 1364. When Sir David Dalrymple was shown one of the charters he promised to correct future editions of his publication. Dalrymple died in 1792 and the correction was never made.
Personal life
Elizabeth's birth date is unknown, but it is said that Elizabeth de Burgh died in 1327. Although, Elizabeth Bruce was certainly alive in 1364 when her brother King David II reconfirmed the estates which Elizabeth and her husband owned. But her death still remains unknown. Given the chronology of her life, it is assumed that she was the daughter of Elizabeth de Burgh and that she got her first name from her mother.
Burial vault
Elizabeth Bruce and Sir Walter Oliphant commissioned a cover to the Oliphant tomb. This cover was made of Tournai marble and is one of the finest incised monuments of its kind in Scotland. The slab can be dated by the design of the armour of the recumbent figure of Sir William Oliphant to circa 1360. Sir William Oliphant died in 1329, some thirty years prior to the creation of the Tournai marble slab depicting him. The most likely reason for the creation of the effigy was to create a tomb fit for a princess.
The most likely reason for Elizabeth not being mentioned by either Fordun or his successors is the fact that Elizabeth was probably born shortly before her mother's death in 1327. More important events therefore overshadowed her birth and early childhood. Her late birth would explain in part why she outlived four and possibly all of her siblings. As the youngest child of King Robert the Bruce and Elizabeth de Burgh, Elizabeth Bruce would have been sixth in line of succession to the Scottish throne.
Kellie Castle
In 1360, Elizabeth Bruce and Sir Walter Oliphant were given the estate and lands of Kellie in Fife by Helena Maxwell, wife of Isaac Maxwell and daughter of Richard Siward.
Peerages
It was during the marriage of Sir Walter Oliphant and Elizabeth Bruce that references to the titles of Lord Oliphant, Lord Aberdalgie and Lord Dupplin first emerged. No explanation for their creation is known other than the fact that of the royal connection.
