Tremorus of Brittany

Saint Tremorus of Brittany is a sixth-century child martyr venerated by the Roman Catholic Church. He was murdered by his stepfather Count Conmore while being educated at a monastery in Carhaix, Brittany. Conmore killed the boy because he hated Christianity. He was the son of Saint Triphina (Triphena), who retired to a convent after her son's murder, and was taught by Gildas the Wise.
