Origin
Meaning and origin of Rozier
The surname Rozier originated in France during the medieval period. It derives from the Old French word 'rosier', meaning rose bush or rose garden. The name likely referred to someone who lived near or tended rose bushes or gardens.
The Rozier surname first appeared in records from the region of Normandy in northern France during the 11th century. Early spellings include Rosiere, Rosyers, and Rousiers. The name spread to other parts of France over the following centuries.
One of the earliest known bearers of the Rozier name was Jehan le Rosier, mentioned in 13th-century records from Normandy. In the 14th century, Jean Rozier was a landholder in the Loire Valley region. Philippe Rozier, born around 1490 in Burgundy, served as a royal gardener.
During the Middle Ages, some Rozier families established themselves in England after the Norman Conquest of 1066. The surname appeared in the Hundred Rolls of 1273 as Rosyer and Rosiere among landholders in Oxfordshire and Buckinghamshire.
Notable individuals with the Rozier surname include Claude Rozier (1570-1638), a French monk and scholar who wrote on religious topics. Philippe Rozier (1703-1776) was a French botanist and member of the Academy of Sciences. Gilbert Rozier (1757-1827) founded an early French agricultural journal.
In the 19th century, Jean-Baptiste Rozier (1815-1879) became a prominent architect in Marseille, designing several churches and public buildings. American aviator Calbraith Perry Rodgers (1879-1912), born Rozier, was among the first to fly across the continental United States in 1911.

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

Is this page using the latest Census data?
Yes. This page is using the latest surname file currently loaded on Name Census, which is 2020. The historical section above also keeps any older Census surname entries we have for Rozier (2000, 2010, 2020).
Does the Census include every surname?
No. The Census Bureau only publishes surnames that appeared at least 100 times in a given decennial Census. That means very rare surnames are excluded entirely, and a surname can appear in one Census release but disappear from a later one if it falls below the reporting threshold.
Why don't the ancestry percentages always add up to exactly 100%?
There are two main reasons: rounding and suppression. The Census Bureau rounds published values, and it may suppress very small cells to protect privacy. For 2020, the Bureau also published raw group counts rather than direct percentages, so Name Census converts those counts back into shares for comparability across census years.
