Born into a farming family at Atcham in Shropshire in 1915, Chibnall was educated at Shrewsbury Priory County Girls' School and Lady Margaret Hall, Oxford, where she was taught by Evelyn Jamison, V. H. Galbraith and F. M. Powicke.
In 1947, she married the biochemist and amateur medieval historian Charles Chibnall, who died in 1988. They had a son and a daughter. Chibnall died in Sheffield on 23 June 2012, at the age of 96.
Marjorie Chibnall took her BLitt at the University of Cambridge on the subject of ecclesiastical law, before moving on for her doctorate to a study of the relations between the mighty Bec Abbey in Normandy and its dependent English priories. She completed her doctorate in 1939 under the supervision of the economic historian Eileen Power. Her early career was spent teaching at the University of Southampton (1941–1943) and the University of Aberdeen (1943–1947).
Chibnall was from 1947 a lecturer in history at Girton College, Cambridge, and from 1953 a fellow of the college, but she relinquished her positions there in 1965 in order to complete her editorial work on the Historia Ecclesiastica of Orderic Vitalis. Four years later she was made a research fellow and subsequently a fellow of Clare Hall, Cambridge, and an honorary fellow of Girton College.
In a career spanning more than six decades, Marjorie Chibnall worked extensively on Anglo-Norman and Norman history. She encouraged much scholarship on these topics, as an active participant at the Battle Conferences on Anglo-Norman history and an editor of their proceedings. Chibnall's editions of the writings of Orderic Vitalis and of Atcham were acclaimed works, as was her biography of the Empress Matilda. She continued to publish when she was well into her nineties. Her last book, a short account of the Normans, was published in 2000.
