Aaron St (2)
Aaron St. (2), is said to have been the founder of the first monastery in Brittany. He flourished in the 6th century, and was eminent for his piety. When St. Malo fled from Britain into Gaul, he was received and hospitably entertained by Aaron, then residing on a little island not far from the present town of Saint Malo. Together with St. Malo, he labored for the conversion of the heathen, and was induced to erect a monastery, over which he presided till his death, in 580. See Hook, Eccles. Biog. s.v.
