From the name of the French city La Rochelle, meaning “little rock”. It first became commonly used as a given name in America in the 1930s, probably due to the fame of actress Rochelle Hudson (1914-1972) and because of the similarity to the name Rachel.
People with the name Jahi have a deep inner desire to use their abilities in leadership, and to have personal independence. They would rather focus on large, important issues, and delegate the details.
Probably from Middle Persian swhr “red” and ab “water”. In the 10th-century Persian epic the Shahnameh this is the name of the son of the hero Rostam. He was tragically slain in battle by his father, who was unaware he was fighting his own son.
