Saint Ramirus was a 6th-century prior of the Saint Claudius Monastery in Leon. He and several others were executed by the Arian Visigoths, who opposed orthodox Christianity. Ramiro originates in Germanic languages and is derived from the words "ragin", which means "counsel or advice", and "meri", which means "great or famous".
