Isabella Plantagenet

Medlands (27 Feb 2024): England, Kings 1066-1603

• 9. ISABELLA (Woodstock Palace, Oxfordshire or Windsor Castle or Marlborough Castle, Wiltshire [12/15] Mar 1274 – ? —, bur Westminster Abbey). The Annals of Worcester record the birth “XVIII Kal Apr” in 1274 of “Edwardo regi Angliæ filiam…Ysabellam”[809], although the date is too close to the recorded birth of her older brother Alfonso for 1274 to be the correct year of Isabella’s birth. The Annals of Winchester record the birth “XVIII Kal Apr…apud Wyndesore” in 1275 of “Alianora regina domino Edwardi regi Angliæ…filiam…Isabellam”[810]. It is uncertain which date “XVIII Kal Apr” is intended to indicate. If the date of Margaret’s birth is recorded correctly in 1275 [sic; 1276] as shown below, Isabella must have been born in 1274 not 1275.
