Saint Cloud was born in 520. When his father was killed in battle in 524 he and his brothers were brought up by their grandmother Saint Clotilde (June 3). His brothers were murdered by their uncles Childebert and Clotaire to prevent them from succeeding to the Frankish throne. Saint Cloud escaped and lived as a hermit, renouncing any claim to the throne.
Later, Saint Cloud was ordained to the holy priesthood, and lived a life of virtue and good works. He died around 560.
