Is-fonds [Margam charters and cartulary rolls] - Margam Abbey charters and cartulary rolls,

The charters date from the foundation of Margam Abbey in c. 1147 until its dissolution in 1536. They include several gifts to the abbey by the earls of Gloucester, as well as royal charters and papal bulls. Together with the rolls they form one of the most complete series of archives of any medieval abbey in Great Britain. Suggested dates (in square brackets) have been supplied from Patterson, Robert B., The Scriptorium of Margam Abbey and the Scribes of Early Angevin Glamorgan (Woodbridge: Boydell Press, 2002), pp. 105-122. Cartae refers to Clark, G.T. (ed.), Cartae et alia Munimenta quae ad Dominium de Glamorgancia pertinent (Cardiff: 1910); History of Margam Abbey refers to Birch, Walter de Gray, A History of Margam Abbey (London: 1897). Following dissolution, the abbey and its lands were acquired by the Mansell family; some of the documentation relating to this is in the Margam estate deeds section.
