Princess Margaret Plantagenet

Royal Descent:

Edward I, King of England m. 1) Eleanor of Castile


Birth:      15 Mar 1275      Windsor Castle, Berkshire

“Contemporary chronicles mention Margaret’s birth as the first event in 1275. It seems not unlikely, then, that Margaret should be identified with the otherwise unknown ‘Isabella’ who is said to have been born at Windsor on 18 kal. (sic) April (15 March) 1275 (Ann. monastici 2.118 [Winchester], 384 [Waverley], and 4.466 [Worcester]). The king and queen cannot be shown to have had a daughter named Isabella.”1

Death:      aft 1333      Brabant

“11 March 1333, Pontefract. To the duke of Brabant. Francis Rauland has brought the duke’s letters to the king, showing how, at the request of Margaret the king’s aunt and at that of the duke, the king had lately granted to Francis the bailiwick of Hastyng Rope” [CCR 1333-1337]; “Green, Lives of the Princesses, following a very late Flemish chronicle, stated that Margaret d 1318, and in this she has been followed by the majority of later authorities. References in official records, however, leave no doubt that Margaret was alive after 1318. Her brother Edward addressed a letter to her on 9 June 1324, and a published charter of Margaret’s is dated by its editor to 1329. The last notice of Margaret in English records indicates that she was living in March 1333”1.

Burial:      St. Michael & St. Gudula Cathedral, Brussels

“She was buried, by the side of her husband, in the church of St. Gudule. In 1617, when the archduke Albert of Austria and his consort, the infant Isabella of Spain, then Duke and Duchess of Brabant, visited Brussels, they raised over the ashes of Duke John and Margaret a splendid tomb of marble, richly adorned, and upon it a lion couchant, of gilded brass, holding an escutcheon of the arms of Brabant, which were a lion rampant or. On a field sable (Jaques le Roy grand theatre sacré de Brabant, vol. i., pt. 1, p. 187).”2

Occupation:      Duchess of Brabant 1294-1312


John II of Brabant, Duke of Brabant

Marriage:      9 Jul 1290      Westminster Abbey

“Margaret and John exchanged promises of marriage (fides data) at Havering on Sunday, 2 July 1290 (C 47/4/5 fol.43b). According to this entry in the ‘Liber’, Margaret’s ‘relevacio’ was on 8 July 1290. Obviously this cannot refer to purification after childbirth. It seems to indicate a ‘relevacio’ such as that celebrated for Hugh de Mortimer’s wife on the morning after her wedding in October 1290. But according to two other accounts Margaret and John were not married at Westminster Abbey until Sunday, 9 July 1290 (C 47/3/22 m.2; C 47/4/4 fol. 43b.). Either the date of the ‘relevacio’ is wrong or the marriage was consummated two days before the actual ceremony, both of which are unlikely, then a ‘relevacio’ could take place before or after the wedding ceremony, as long as it was prior to consummation.”3
