"The Stowe Missal is a manuscript of the late 8th or early 9th century, with alterations in later hands, most of them written by one Moelcaich, who signs his name at the end of the Canon, and whom Dr. MacCarthy identifies, not very convincingly, with Moelcaich MacFlann, c. 750.It was discovered abroad, in the 18th century, by John Grace of Nenah, from whom it passed to the Duke of Buckingham's library at Stowe.
