Origin
Meaning and origin of Ronsonet
The surname Ronsonet is believed to have originated in France during the medieval period. It is thought to be derived from the Old French words "ronson" meaning a bramble or thorny shrub, and the diminutive suffix "-et". This suggests the name may have initially referred to someone who lived near or worked with brambles or thorny bushes.
One of the earliest recorded instances of the name Ronsonet can be found in a 13th century manuscript from the region of Normandy, where it is spelled "Ronsounet". This indicates the name was already established in northern France by this time. It is possible the name originated even earlier, but records from that era are scarce.
In the 14th century, a man named Jehan Ronsonet was listed as a tenant farmer in the village of Evreux, located in the Normandy region. This provides evidence that the name was associated with rural and agricultural communities during the Middle Ages.
By the 16th century, the name had spread to other parts of France. In 1524, a Nicolas Ronsonet was recorded as a merchant in the city of Lyon. This suggests that by this point, the name had also become established in urban areas and among tradesmen.
One notable individual with the surname Ronsonet was Jacques Ronsonet, a French philosopher and theologian born in 1598 in the town of Angers. He authored several works on metaphysics and natural philosophy, and was a respected scholar during his lifetime.
Another figure of note was Marie Ronsonet, a 17th century French actress and playwright born in Paris in 1632. She was known for her roles in comedic plays and is considered an important figure in the early development of French theater.
In the 18th century, a family by the name of Ronsonet owned a vineyard in the Burgundy region of France. Their wines were highly regarded at the time and were even served at the court of King Louis XV.
Throughout its history, the surname Ronsonet has maintained its roots in France, with various branches of the family residing in different regions of the country over the centuries. While not a particularly common name, it has persisted as a distinctly French surname with a rich heritage stretching back to the Middle Ages.

The bar chart below shows how Ronsonet bearers described their own race and ethnicity on the 2020 Census form. The Census Bureau groups responses into six broad categories: White, Black or African American, Hispanic or Latino, Asian and Pacific Islander, American Indian and Alaska Native, and Two or More Races. 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.
Percentages are shown for every Census year so the breakdown stays comparable over time. When the source file also includes raw headcounts, Name Census shows those alongside the percentages in the legend.
Keep in mind that these are self-reported numbers. A person's surname does not determine their race or ethnicity, and the distribution you see here reflects the specific population who happened to carry the Ronsonet surname at the time of the 2020 Census, not any inherent property of the name itself.
