Born to a noble Gallo-Roman family at Vannes, Brittany, St. Albinus was a monk and from 504 A.D. Abbot of Tintillac (which no longer stands; its location has not been satisfactorily identified).

Another tradition states that he clashed with King Childebert, who had imprisoned a woman called Etherie, from Douille near Angers.

Unable to secure her release Albinus visited her in prison, and the soldier who tried to resist him fell dead at his feet.

Later the tradition was reinforced by a miracle recorded in the 10th century, when the walled town of Guérande, near the mouth of the Loire, prayed to St. Albinus for help and found their attackers miraculously defeated.

In the Middle Ages, Nicholas Belfort notably wrote describing miracles performed at the tomb of St. Aubin after the year 1000 AD.
