Notes on the parentage of Gwladus and Margaret, daughters of Llwelyn ap Fawr:

Complete Peerage (IX: 276) and Royal Ancestry both give Gwladus as a daughter of Joan of England. Royal Ancestry gives Margaret as an illegitimate daughter of Llywelyn.

The Oxford Dictionary of National Biography says that Joan was "probably" the mother of Gwladus and Margaret.

In The American Genealogist 41:99 (1965), Walter Lee Sheppard notes that "DNB's account gives Joan only the son David with Helen as probable. Lloyd's History of Wales [...] includes a chart so drawn as to make the maternity of the daughters questionable, and omits Angharad altogether. Prof. Thomas Jones Pierce in his article on Joan in the Dictionary of Welsh Biography names David, but does not mention the daughters at all; but then his cited sources are ony DNB and Lloyd's History of Wales in earlier editions. The correspondence of the writer with Sir Anthony Richard Wagner, Garter Principal King of Arms, however, indicates that all these daughters, with the exception of Gwladys, have been accepted by Major Francis Jones, best known authority on Welsh pedigrees, and based on British Museum Manuscript Add. 15041, on folio 12a, which shows Joan to be mother of David, Gwenlian, Angharad, and Margaret. It is interesting to note that [Complete Peerage] 9:276, under Mortimer of Wigmore, identifies Gwaldys as Joan's daughter."

Later in the same publication, TAG 41:22, Sheppard provides an addendum, first quoting a letter from E. D. Jones, Librarian of the National Library of Wales: "Robert Vaughan of Hengwrt, a reliable seventeenth century authority, makes Gwladys full sister to Gruffydd, therefore the daughter of Tangwystl. He makes Gwenllian, Angharad and Marred (Margaret) to be daughters of Joan. I am inclined to accept the view that Gwladys Ddu was the daughter of Tangwystl, but in the absence of contemporary records it is not wise to be too dogmatic." Sheppard then continues: "Sir Anthony Richard Wagner KCVO, Garter Principal King of Arms, in a letter to the writer dated 24 Sept. 1964, states that he would accept Margaret as Joan's daughter and, presumably, the other daughters, except Gwladys. He refers to Major Francis Jones and the previously cited British Museum Additional MS, which shows Joan to be mother of David, and points out that the chronology also fits."

Peter C. Bartrum's Welsh Genealogies (1974-83, searchable here; use the search term "Gruffudd ap Cynan 04"), gives Tangwystl as the mother of Gwladus and Joan as the probable mother of Margaret.

William Addams Reitwiesner's "The Children of Joan, Princess of North Wales," in The Genealogist 1:80, Spring 1980, argues that we have no certain basis for regarding Joan as the mother of any of Llywelyn's daughters.

On 9 April 1999, Douglas Richardson posted the following to SGM: "As for the Welsh tradition that any son, legitimate or otherwise, could make a claim to succeed Llywelyn, you may recall that Llywelyn and his son, David, went out of their way to have David recognized as Llywelyn's sole heir, to the exclusion of Llywelyn's illegitimate sons. To accomplish this, they had Llywelyn's wife, Joan, legitimized. The legitimization of Joan was no small feat seeing she was surely born out of wedlock to King John's mistress. Also, they sent David to England to be recognized as Llywelyn's sole heir by the English overlord, David's own uncle, King Henry III. Interestingly, the records of this trip show that David was accompanied by none other than his sister, Gladys. Due to the nature of this trip, it seems odd that Gladys would accompany David on this trip, UNLESS she too was a legitimate child of Llywelyn and Joan. These two pieces of evidence convince me that Gladys was legitimate."
