Origin
The surname Owensby has its origins in the British Isles, specifically in England. It is believed to have derived from the Old English words "Owenes" and "by," meaning "Owen's village" or "Owen's settlement." This suggests that the name likely originated from a place name, referring to a locality where someone named Owen or a variation of that name resided.
The earliest recorded instances of the surname Owensby can be traced back to the 13th century in various historical records, such as the Hundred Rolls of 1273. These ancient documents often mentioned people's names alongside their places of residence or origin, which could have given rise to the surname Owensby.
One notable historical figure associated with this surname was Sir John Owensby, a prominent landowner and knight who lived in the 14th century. Records indicate that he was born in Owensby, a small village in the county of Lincolnshire, England, in 1325 and died in 1397.
Another individual of note was Richard Owensby, a merchant and alderman in the city of London during the 16th century. He was born in 1521 and played an influential role in the city's trade and governance until his death in 1589.
In the 17th century, the name Owensby appeared in various parish records and tax rolls, indicating its widespread use across different regions of England. One such example was William Owensby, a farmer from Oxfordshire, who was born in 1632 and lived until 1701.
During the 18th century, the surname Owensby was also found in parts of Scotland and Ireland, potentially due to migration and intermarriage between families from different parts of the British Isles. A notable bearer of the name was James Owensby, a Scottish philosopher and writer born in 1745 in Edinburgh. He authored several influential works on ethics and political theory before his death in 1819.
In the 19th century, the surname Owensby continued to be documented in various historical records across the United Kingdom. One prominent figure was Elizabeth Owensby, a renowned poet and novelist from Wales, born in 1825. Her literary works gained widespread recognition during her lifetime, and she is remembered as a significant figure in Welsh literature until her passing in 1892.

The bar chart below shows how Owensby 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 Owensby surname at the time of the 2020 Census, not any inherent property of the name itself.

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.
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.
