Leion is a Greek-derived name meaning "lion," symbolizing strength and courage. It originated during the Middle Ages and was often given to children born around the summer solstice due to its association with solar power. Throughout history, Leion has been carried by notable figures such as an Argonaut in Greek mythology and Saint Leion, a Christian martyr. Today, it is chosen for its unique sound and powerful meaning, though it remains relatively rare worldwide.
