The modern establishment has had four Lord Abbots since its inception:
Father Michael Sherry, O.C.S.O. ( d. 2003) Superior of the foundation between 1946 and its inauguration in 1948. Father Michael was the Prior, never the abbot. Nunraw was elevated from a priory to an abbey in 1948, Dom Columban Mulcahy being the first abbot.
* Now in England, but at the time of its foundation, part of the Scottish kingdom of David I.
** Filiation from Mellifont Abbey in Ireland, founded 1142.
*** If this existed, it was shortly afterwards replaced by a Premonstratensian establishment.
**** In the line of filiation from Melrose (above).
