Origin
Meaning and origin of Aubourg
The surname Aubourg is of French origin, believed to have emerged in the region of Normandy during the Middle Ages. It is derived from the Old French words "aub" and "bourg," which together signify "a hamlet near a stream or brook." This suggests that the name was initially associated with individuals who resided in such settlements.
One of the earliest recorded instances of the name Aubourg can be found in the medieval records of Normandy, dating back to the 12th century. These documents mention several individuals bearing variations of the name, such as Auborc, Aubourc, and Aubourg, indicating the fluidity of spellings during that era.
It is worth noting that the name Aubourg does not appear in the Domesday Book, the renowned survey commissioned by William the Conqueror in 1086. However, its absence from this particular record does not necessarily imply that the name did not exist at that time, as many surnames were yet to be formalized.
Among the notable individuals who bore the surname Aubourg throughout history, one can mention Jean Aubourg (1504-1572), a prominent French Renaissance poet and playwright from Normandy. His works, including the play "La Tragedie de Sainte Agnes," were celebrated during his lifetime and contributed to the literary landscape of the era.
Another figure of historical significance was Marie Aubourg (1676-1741), a French midwife and author who wrote extensively on childbirth and maternal health. Her treatise, "L'Art des Accouchements," was widely circulated and influential in shaping medical practices related to obstetrics in the 18th century.
In the realm of military service, the name Aubourg is associated with General Pierre Aubourg (1784-1857), a distinguished French officer who fought in the Napoleonic Wars. His bravery and leadership earned him numerous honors, including the prestigious Legion of Honor.
Moving to the artistic realm, one cannot overlook the contributions of the sculptor Émile Aubourg (1829-1900), whose works adorned many public spaces and museums in France during the late 19th century. His most notable pieces include the statue of Joan of Arc in Rouen and the allegorical figure "La République" that stands at the entrance of the Palais du Louvre in Paris.
Lastly, the name Aubourg also has ties to the field of education through the figure of Marie-Louise Aubourg (1864-1938), a pioneering French educator and advocate for women's rights. She founded several schools dedicated to providing quality education for girls and played a pivotal role in advancing the cause of gender equality in France during the early 20th century.

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