Origin
The surname JONASSAINT has its origins in the French language and is believed to have originated in the region of Normandy, France, during the medieval period. It is derived from a combination of the French words "Jonas" and "saint," which translate to "John" and "saint," respectively.
The name is thought to have been initially used as a descriptive surname, referring to individuals who were particularly devout or associated with religious institutions dedicated to Saint John. Some historical records suggest that the earliest bearers of this surname may have been members of monastic orders or individuals employed by churches or monasteries dedicated to Saint John.
One of the earliest recorded instances of the JONASSAINT surname can be found in the "Cartulaire de l'Abbaye de Fontenay," a medieval manuscript dating back to the 12th century. This document mentions a certain "Radulphus Jonassaint," who was a landowner in the region of Normandy during that period.
In the 13th century, the JONASSAINT surname appeared in the "Livre des Bourgeois de Rouen," a register of the citizens of Rouen, a city in northern France. This record includes the name of a merchant named "Guillaume Jonassaint," who was active in the city's trade guilds during that time.
During the 14th century, the JONASSAINT surname was mentioned in the "Cartulaire de l'Abbaye de Saint-Wandrille," a collection of charters and documents related to the Abbey of Saint-Wandrille in Normandy. This document references a monk named "Frère Pierre Jonassaint," who resided at the abbey during the latter part of that century.
In the 15th century, a notable figure bearing the JONASSAINT surname was "Jean Jonassaint" (1412-1478), a French cleric and scholar who served as the Bishop of Bayeux in Normandy. He was known for his contributions to religious literature and his efforts to promote education in the region.
Another prominent individual with the JONASSAINT surname was "Nicolas Jonassaint" (1548-1617), a French jurist and legal scholar who served as a judge in the Parlement of Normandy. He was renowned for his expertise in civil and ecclesiastical law and wrote several influential treatises on legal matters.
These examples demonstrate the historical presence of the JONASSAINT surname across various regions of France, particularly in Normandy, and its association with religious institutions, education, and legal professions throughout the medieval and Renaissance periods.
Demographics
Among Census respondents with the surname Jonassaint, the largest self-reported group is Black at 86.9%. The next largest groups are Hispanic (6.5%) and Two or More Races (3.7%).
The bar chart below shows how Jonassaint 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 Jonassaint surname at the time of the 2020 Census, not any inherent property of the name itself.
