Origin
Meaning and origin of Rozan
The surname Rozan is believed to have originated in Normandy, France during the medieval period. It is thought to be derived from the Old French word "rozain," meaning a rose bush or rose garden.
One of the earliest known records of this surname can be found in the Domesday Book of 1086, where it was spelled "Rosayn." This suggests that the name may have been used by those who cultivated roses or worked in rose gardens.
In the 12th century, a family bearing the name Rozan was documented in the region of Calvados, Normandy. This area was known for its abundance of rose gardens and the cultivation of roses for perfumes and medicinal purposes.
During the 13th century, a knight named Sir Geoffroy Rozan was recorded as having participated in the Seventh Crusade, led by King Louis IX of France. His name appears in chronicles of the time, highlighting the prominence of the Rozan family during this era.
In the 15th century, a notable bearer of the name was Jean Rozan, a French poet and scholar who lived from 1425 to 1492. He was renowned for his works on classical literature and his translations of ancient Greek texts.
Another distinguished individual with the surname Rozan was Étienne Rozan, a French architect who lived from 1572 to 1638. He is credited with designing several noteworthy buildings in Paris, including the Church of Saint-Gervais-et-Saint-Protais and the Hôtel de Beauvais.
In the 18th century, a French botanist named René-Auguste Rozan gained recognition for his contributions to the study of plant life. He was born in 1732 and passed away in 1810, leaving behind a legacy of botanical research and writings.
During the 19th century, the name Rozan was found in various regions of France, including Burgundy, where a village called Rozan-sur-Ouche still exists today. This suggests that the name may have been associated with specific locations or landholdings in the past.

The bar chart below shows how Rozan 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 Rozan surname at the time of the 2020 Census, not any inherent property of the name itself.

Does the Census include every surname?
