Origin
Meaning and origin of Delozier
The surname DELOZIER has its origins in France, believed to have emerged sometime in the late medieval period, around the 13th or 14th century. It is thought to derive from the Old French words "de" meaning "of" or "from," and "l'ozier," referring to a willow tree or willow grove. This suggests the name may have initially been associated with someone who lived near a willow tree or a place known for its abundance of willows.
Early variations of the spelling include Delozieres, Delozières, and Delosier, reflecting the regional dialects and language evolution over time. The name is likely rooted in a specific location or region where willows were prevalent, though the exact origin remains uncertain.
One of the earliest recorded instances of the name appears in the Parisian tax rolls from the late 15th century, where a Jacques Delozieres is listed as a resident. This provides evidence of the name's existence and use in France during that era.
In the 16th century, a prominent figure bearing the DELOZIER surname was Pierre Delozier, a merchant and landowner from the Normandy region. Historical records indicate he was born in 1522 and lived until 1598, playing a role in the local economy and community affairs.
Another notable individual was Jean-Baptiste Delozier, a French military officer who served during the Thirty Years' War in the early 17th century. Born in 1587, he rose to the rank of captain and played a part in several significant battles before his death in 1642.
Moving into the 18th century, Marie-Françoise Delozier, born in 1723, was a celebrated artist and painter known for her intricate portraiture and landscapes. Her works were highly regarded during her lifetime and can still be found in various art collections throughout Europe.
In the 19th century, Charles-Edouard Delozier, born in 1814, was a renowned architect and urban planner who contributed to the redesign and modernization of several French cities, including Lyon and Bordeaux. His innovative designs and attention to detail left a lasting impact on the urban landscapes of his time.
While the DELOZIER surname originated in France, it has since spread to other parts of the world through migration and emigration, with notable individuals bearing this name across different eras and regions, reflecting the rich history and diversity of this surname.

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.

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 Delozier surname at the time of the 2020 Census, not any inherent property of the name itself.

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 Delozier (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.
