Show ContentsLeonardi History, Family Crest & Coats of Arms

The distinguished surname Leonardi can be traced back to the ancient and beautiful region of Venice. Although people were originally known only by a single name, it became necessary for people to adopt a second name to identify themselves as populations grew and travel became more frequent. The process of adopting fixed hereditary surnames was not complete until the modern era, but the use of hereditary family names in Italy began in the 10th and 11th centuries. Italian hereditary surnames were developed according to fairly general principles and they were characterized by a profusion of derivatives coined from given names. The most common type of family name found in the region of Venice is the patronymic surname, which is derived from the father's given name. During the Middle Ages, Italians adopted the patronymic system of name-making because it perfectly complemented the prevailing Feudal System. In Italy the popularity of patronymic type of surname is also due to the fact that during the Christian era, people often named their children after saints and biblical figures. The surname Leonardi came from the Old German name Leonhard, which is composed of the elements lewo or lion and hardhu, which means strong, brave.
