Leonard

Means "brave lion", derived from the Germanic elements lewo "lion" (of Latin origin) and hard "brave, hardy". This was the name of a 5th-century Frankish saint from Noblac who is the patron of prisoners and horses. The Normans brought this name to England, where it was used steadily through the Middle Ages, becoming even more common in the 20th century.
