Origin
Meaning and origin of Giansanti
The surname GIANSANTI has its origins in Italy, dating back to the late medieval period around the 13th or 14th century. It is believed to have originated from the regions of Tuscany and Umbria, where the name was initially recorded in various forms such as Giansante, Giansanti, and Giansante.
This surname is thought to be derived from the Italian personal name "Giansante," which itself is a combination of the names "Giovanni" and "Sante." The name "Giovanni" is the Italian form of the Hebrew name "Yohanan," meaning "Yahweh is gracious," while "Sante" is derived from the Latin word "sanctus," meaning "holy" or "saintly."
One of the earliest recorded instances of the surname GIANSANTI can be found in the archives of Florence, Italy, where a certain Giansante di Bartolomeo was mentioned in a document dated 1325. Another early reference is from the town of Perugia in Umbria, where a family by the name of Giansanti is documented as having lived in the 15th century.
Throughout the centuries, several notable individuals have borne the surname GIANSANTI. One such figure was Pietro Giansanti (1508-1573), an Italian artist and architect who worked in various cities, including Rome, during the Renaissance period. Another was Giansante Comotti (1775-1848), an Italian physician and naturalist who made significant contributions to the field of botany.
In the 19th century, a family of GIANSANTI is recorded as having lived in the town of Montefalco, Umbria. One member of this family, Luigi Giansanti (1820-1892), was a prominent lawyer and politician who served as a deputy in the Italian parliament.
Another notable bearer of the name was Amerigo Giansanti (1892-1972), an Italian actor and film director who appeared in several silent films during the early 20th century. He is particularly remembered for his role in the 1916 film "Quo Vadis?"
While the surname GIANSANTI is not among the most common Italian surnames, it has a rich history and has been borne by individuals from various walks of life, including artists, scientists, politicians, and entertainers.

There are two main reasons: rounding and suppression. The Census Bureau rounds published values, and it may suppress very small cells to protect privacy.
