Dear Newsgroup ~
After I made my post yesterday regarding Mary Douglas, Duchess of Rothesay, the daughter-in-law of King Robert III of Scotland, I surveyed many published secondary sources regarding Scottish royal and noble families, all of whom with two exceptions referred to this woman as Marjory Douglas. This includes the recent work published in 2006 by the historian, Bruce McAndrew, entitled "Scotland's Historic Heraldry."
As to what sources actually refer to her as Mary Douglas, the first source I found was Drummond, Genealogy of the Most Noble and Ancient House of Drummond (1831): 77, which reads as follows:
“David the Prince and Duke of Rothsay : He married Marie or Marjorie Douglas daughter of Archbald the Grim, third Earle of Douglas.” END OF QUOTE.
As we can see, the above source refers to her as both Mary and Marjory Douglas.
As to the second source which refers to her as Mary Douglas, it is surprisingly found in "Additional Corrigenda, etc." published in 1898 in Volume 8 of an earlier edition of Complete Peerage.
On page 534, the following information is provided:
"In his preface to vol. iv of the Exchequer Rolls (p. clxxi) the late G. Burnett, Lyon King of Arms, calls attention to a Walter de Haliburton, who married Lady Mary Douglas, widow of David, Duke of Rothesay [d. 26 March 1402], and gives it as his opinion that this Walter was the son to the Walter of Dirletoun, with whom the article in the present work begins. Walter de Haliburton, husband to the Duchess of Rothesay, drew her pension from the customs of Edinburgh and Linlithgow from 1404 to 1421, in which year - at Pentecost - she was dead. It is therefore possible that Walter the Hostage and the Treasurer was the widower and the elder brother of John, but it is clear from the Charters relating to the annuity from Tranent, that John, Lord Halyburton of Dirletoun, 1446/7, was son of the Walter de Halyburton, who married Isabel, Countess of Ross, dau. of the Duke of Albany. Whether the two Walters were father and son, or what relationship they bore to each other, is matter of considerable doubt. [Ex. Inform. W.A. Lindsay, Q.C., Windsor Herald.]." END OF QUOTE
We see above that the editor of Complete Peerage was informed by Mr. Lindsay before 1898, as to the correct given name of Mary Douglas, Duchess of Rothesay. Yet by 1916, this correction was forgotten and Duchess Mary was called Marjory in the next edition of Complete Peerage published in that year.
It is strange indeed that Mr. Burnett's original observations as to the correct name of Mary Douglas should be included in a volume of Complete Peerage published in 1898, and yet forgotten in the next edition of Complete Peerage published in 1916. But that is apparently what happened.
Mr. Lindsay correctly notes that there were two Walter de Haliburton's living at the same time, one of whom married Mary Douglas, Duchess of Rothesay, and the other who married Isabel Stewart, Countess of Ross, daughter of Robert Stewart, Duke of Albany. It is sometimes asserted that Walter, husband of Mary, was the son of the Walter, husband of Isabel. This could well be true.
Mr. Lindsay, however, implies that this is doubtful. Mr. Lindsay then states that John de Haliburton, 1st Lord Haliburton, in the next generation was the son of Walter, husband of Countess Isabel. Yet Scots Peerage and Complete Peerage both assign John as the son of Walter, husband of Duchess Mary. Without considerable more research, it is impossible to tell which Walter was the father of John in the next generation. Hopefully someone with better particulars can address this question.
One last comment. As I noted in my earlier post, Mr. Burnett stated in 1880 that Mary Douglas, Duchess of Rothesay, was called "Elizabeth" in a clerical slip in the ‘Rotuli Scotiae,’ ii, p. 197.” The actual record is published in Rotuli Scotiae in Turri Londinensi 2 (1819): 197, and may be viewed at the following weblink:

The above record is a safe conduct granted in 1411 by King Henry IV of England to Elizabeth, Duchess of Rothesay, whom he styles his "kinswoman" [consanguineam].
King Henry IV of England and Mary, Duchess of Rothesay, were in fact 4th cousins to one another, by virtue of their common descent from Sir Alexander Comyn, Earl of Buchan (died 1290). This acknowledged kinship provides additional evidence that Duchess Mary's mother, Joan of Moray, was in fact the daughter and heiress of Maurice of Moray, Earl of Strathearn (a Comyn descendant), as I indicated in an earlier thread here on the newsgroup.
