The history of the last name Rosar

The surname Rosar is believed to have originated in the Veneto region of northeastern Italy during the medieval period. It is derived from the Italian word "rosa," meaning "rose," and was likely an occupational name given to those who cultivated or sold roses.

One of the earliest recorded instances of the name Rosar can be found in a document from the city of Verona, dated 1289, which mentions a certain "Petrus Rosar." This suggests that the name was already established in the area by the late 13th century.

In the 14th century, the name appeared in various records from the Venetian Republic, such as the "Libro d'Oro" (Book of Gold), which listed noble families of the region. One notable individual from this period was Giovanni Rosar (c. 1320-1389), a wealthy merchant and landowner from the city of Vicenza.

The Rosar name also had variants and localized spellings, such as "Rosario" and "Rosari," which were more common in southern Italy and Sicily. In the 15th century, a Sicilian family bearing the name Rosari gained prominence, with members serving as military officers and advisors to the ruling dynasties.

As the Renaissance period dawned, the name Rosar spread beyond Italy, carried by merchants and travelers. In the 16th century, a Spanish explorer named Juan Rosar (c. 1510-1583) accompanied Hernán Cortés on his expeditions to the New World and is believed to have settled in Mexico.

In the 17th century, the Rosar name appeared in various European countries, including France, where a notable figure was the poet and playwright Pierre Rosar (1637-1707), whose works were acclaimed during the reign of Louis XIV.
