Origin
Meaning and origin of Dastolfo
The surname DASTOLFO is of Italian origin, with its roots traced back to the 13th century in the northern regions of Italy, particularly in the areas around Lombardy and Emilia-Romagna. The name is derived from the combination of two words: "da," meaning "from," and "Stolfo," which is believed to be a variation of the Germanic name "Stolfo" or "Stolf," meaning "wolf."
One of the earliest recorded instances of the DASTOLFO surname can be found in the 14th-century Venetian archives, where a merchant named Franceso DASTOLFO is mentioned conducting trade in the Mediterranean region. This suggests that the name had already established itself in Italy during that time.
In the 15th century, a renowned artist and sculptor named Girolamo DASTOLFO (1433-1501) gained recognition for his work in several churches and cathedrals across Italy, including the Basilica di Santa Maria delle Grazie in Milan and the Duomo di Cremona.
During the Renaissance period, the DASTOLFO family played a significant role in the intellectual and cultural circles of Italy. Ludovico DASTOLFO (1508-1572), a prominent humanist and philosopher, authored several influential works on ethics and political theory, which were widely read and discussed among scholars of the time.
In the 17th century, the DASTOLFO name is associated with the noble family of the same name in the city of Verona. Giulio DASTOLFO (1622-1687), a member of this illustrious family, served as a diplomat and ambassador for the Venetian Republic, representing its interests in various European courts.
Moving forward to the 19th century, Giuseppe DASTOLFO (1819-1892), a renowned Italian composer and conductor, gained recognition for his operas and symphonic works, which were performed in major theaters across Europe.
Throughout its history, the DASTOLFO surname has maintained a strong presence in various regions of Italy, with numerous individuals bearing this name contributing to various fields, including art, literature, politics, and academia.

When a category has too few respondents for a given surname, the Bureau suppresses the figure to protect individual privacy, which is why some names show fewer than six slices.
