Origin
The surname Oger is of French origin, deriving from the Old French personal name Ogier, which itself comes from the Germanic name Otger. This name is composed of the elements "ot" meaning "wealth" and "ger" meaning "spear." The name likely emerged in the regions of northern France and Normandy during the early medieval period.
One of the earliest recorded instances of the name Oger can be found in the French epic poem "La Chevalerie Ogier de Danemarche" (The Chivalry of Ogier the Dane), which dates back to the 12th century. This poem tells the story of a legendary knight named Ogier the Dane, who fought alongside Charlemagne. It is believed that this literary work contributed to the popularity of the name Oger in France during the Middle Ages.
In England, the name Oger appears in the Domesday Book of 1086, which was a comprehensive survey of landowners commissioned by William the Conqueror. The Domesday Book records several individuals with the name Oger or variants such as Ogerus, suggesting that the name had spread to England by the late 11th century.
One notable bearer of the surname Oger was Jean Oger (c. 1300-1370), a French military commander who served under King John II during the Hundred Years' War. He played a crucial role in the Battle of Poitiers in 1356, where he was taken prisoner by the English.
Another significant figure was Jean-François Oger (1672-1720), a French explorer and navigator who led several expeditions to the West Indies and the Gulf of Mexico in the early 18th century. He is credited with mapping and charting many islands and coastal regions in the Caribbean.
In England, one notable bearer of the name was Richard Oger (c. 1560-1645), a wealthy merchant and landowner who served as the Sheriff of Cambridgeshire and Huntingdonshire in 1616. He was also a prominent benefactor to the University of Cambridge.
The name Oger has also been associated with various place names, such as Ogereau in France and Ogersheim in Germany, further indicating its historical presence and geographical spread.
While the surname Oger is not among the most common surnames today, it has a rich historical legacy that can be traced back to medieval times, with bearers of the name playing important roles in military, exploration, and commercial endeavors throughout the centuries.
Demographics
Among Census respondents with the surname Oger, the largest self-reported group is White at 90.9%. The next largest groups are Black (5.1%) and Hispanic (3.0%).
The bar chart below shows how Oger 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 Oger surname at the time of the 2020 Census, not any inherent property of the name itself.
