Princess JOAN PLANTAGENET of England
“Preparations for Eleanor of Castile’s confinement were underway on 7 December 1264, and her churching was imminent on 3 February 1265 (CLR 5.150, 160). On Sunday, the feast of the Conversion of St. Paul, 49 Henry III (25 January 1265), 13s. 4d. were paid for medicines for Eleanor’s use; P.R.O. E 101/350/1, m.1, the entire document printed in G.E. Trease, ‘The Spicers and Apothecaries of the Royal Household in the Reigns of Henry III, Edward I and Edward II’, Nottingham Medieval Studies, 3 (1959) 40-41 (although the account’s ‘Lady Eleanor’ is mistakenly identified in the edition as Queen Eleanor of Provence, who was actually in France in January 1265, and who in any event would certainly have been styled ‘domina Regina’ by the wardrobe clerks). The child born in January 1265 must have been Joan.”1
