In page Margaret de Quincy, Countess of Lincoln:

"

Margaret was a careful overseer of her property and tenants, and gracious in her dealings with her son's children, neighbours and tenants.[1] She received two papal dispensations in 1251, the first to erect a portable altar; the other so that she could hear mass in the Cistercian monastery.[2] Margaret died in March 1266[3] at Hampstead. Her death was recorded in the Annals of Worcester and in the Annals of Winchester.[citation needed] She was buried in The Order of St. John Cemetery, Farringdon, London.
