In page Margaret of Hereford:

"

Margaret died on 6 April 1197 and was buried in Llanthony Secunda Priory in Gloucester which had been founded by her father and where her mother, Sibyl had entered a religious life after her husband's untimely death. Margaret herself had made endowments to the Augustinian priory. Two years following Margaret's death, King John confirmed the possessions of Llanthony Secunda Priory by charter which was dated 30 July 1199. These included the donation of duas partes de Onedesleye made by Margar de Bohun in accordance with the division made inter ipsam et Luciam suam sororem.[citation needed] On 28 April 1200, King John recreated the earldom of Hereford for Margaret's grandson Henry, of whom she had had custody during his minority.
