Abran was a 6th-century Irish hermit who settled in Brittany. Born in Ireland, he was the brother of Gibrian and part of a large group of siblings, including five brothers and three sisters, who all dedicated themselves to religious life. Following their commitment to God, the siblings traveled to Brittany together. Abran established his hermitage along the Marne River, occupying a site that had been granted to him by Saint Remigius.
