Sinibaldi

Sinibaldi is an Italian surname. It is a patronymic surname, derived from a personal name, "Sinibaldo." The name "Sinibaldo" itself is of Germanic origin, composed of the elements sin (meaning "old") and bald (meaning "bold" or "brave"). Therefore, "Sinibaldo" essentially meant "bold elder" or "brave old one."

Surnames like Sinibaldi arose during the Middle Ages as populations grew and it became necessary to distinguish individuals who shared the same given name. The surname would then be passed down through generations, identifying descendants of the original "Sinibaldo."

The surname is most commonly found in Italy, particularly in central regions. Variations of the name may exist. The surname, like others of Italian origin, can sometimes be found amongst diaspora populations, particularly in countries with significant Italian immigration.
