Origin
The surname BAYZE is believed to have originated in the northern regions of France during the Middle Ages. It is derived from the Old French word "baies," which means "berries" or "small fruit." This suggests that the name may have been originally associated with individuals who cultivated or traded in berries or other small fruits.
One of the earliest recorded instances of the name BAYZE can be found in the Livre Terrier de Picquigny, a medieval land registry document from the Somme region of northern France, dated around 1280 AD. This document mentions a certain "Jehan Bayze" as a landowner in the village of Picquigny.
In the 14th century, the name BAYZE appears in the tax records of the city of Amiens, also located in northern France. These records mention a "Jacques Bayze" who was a merchant and landowner in the city during the 1340s.
During the 16th century, the name BAYZE can be found in the parish records of the village of Tilloloy, near Abbeville in the Somme region. These records mention the birth of a "Marie Bayze" in 1572, the daughter of a local farmer named "Pierre Bayze."
One notable individual with the surname BAYZE was Jean-Baptiste Bayze, a French playwright and poet who lived in the 17th century (born in 1647, died in 1712). He was known for his satirical plays and his involvement in the literary circles of Paris during the reign of Louis XIV.
Another notable figure was Étienne Bayze, a French botanist and naturalist who lived in the 18th century (born in 1725, died in 1798). He was known for his extensive studies of the flora and fauna of the French colonies in the Caribbean and South America.
In the 19th century, the name BAYZE can be found in the records of the town of Dieppe in northern France. These records mention a "Charles Bayze" who was a ship's captain and merchant operating out of Dieppe during the 1830s and 1840s.
The surname BAYZE is also associated with the village of Bayze in the Aube region of northeastern France. This village likely derived its name from the same Old French word "baies," suggesting that it may have been a center for berry cultivation or trade in the past.
While the name BAYZE is not particularly common today, it has a rich history rooted in the northern regions of France, where it was associated with various occupations and locations related to the cultivation and trade of berries and other small fruits.
Demographics
Among Census respondents with the surname Bayze, the largest self-reported group is Hispanic at 80.4%. The next largest groups are White (15.0%) and Black (1.9%).
The bar chart below shows how Bayze 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 Bayze surname at the time of the 2020 Census, not any inherent property of the name itself.
