The author concludes: "Our understanding of this period is hampered by a number of factors. Accidental fires and those caused by enemy action destroyed much written material in Irish monastic houses. Moreover, Irish religious communities are accepted as having been some of the world's worst record keepers. To the best of available knowledge the monastic settlement on Inishmurray was founded circa 520 A.D. and ended in the latter part of the twelfth century..."
St. Molaise in known as the confessor to St. Columba (Colm Cille), which may be evidence of the ties between the monastery at Inishmurray and Columba's center at Iona in Scotland. As confessor, St. Molaise would have mandated St. Colm Cille exile from Ireland after the terrible slaughter Colm Cille caused at the Battle of Cúl Dreimhne in 561 (the Battle of the Books). It was said that Colm Cille's used his cloak to walk over the water to Inishmurray. (McGowan, Joe. Inishmurray: Gale, Stone, and Fire : Portrait of a Fabled Island. Mullaghmore, Co. Sligo: Aeolus, 1998. 11-12.)
St. Molaise was also referred to as Muirdeach, which may have been the island's original name's in Irish. Successor abbots on Inishmurray appear to have also used the name Molaise.
