Origin
Meaning and origin of Hartsock
The surname Hartsock is of English origin, deriving from a combination of the Old English words "heorot" meaning hart or deer, and "cocc" meaning a small hill or hillock. This suggests that the name likely originated in areas where deer were found near hillocks, perhaps indicating an occupation or place of residence.
Hartsock is believed to have first appeared in records during the 13th century in various counties across England, including Yorkshire, Derbyshire, and Staffordshire. Early spellings of the name included Hertesoc, Hertesoke, and Hertsock.
One of the earliest recorded instances of the name can be found in the Subsidy Rolls of Staffordshire from 1327, which lists a John Hertesoc. Additionally, the Hundredorum Rolls of 1273 mention a William Hertesoke in Derbyshire.
During the medieval period, the name Hartsock was also associated with specific place names, such as Hartsock in Derbyshire and Hartsock Hill in Yorkshire. These locations likely contributed to the development and spread of the surname.
Notable individuals throughout history bearing the surname Hartsock include:
1. William Hartsock (c. 1590 - 1660), an English landowner and member of the gentry in Derbyshire.
2. John Hartsock (1726 - 1798), an American Revolutionary War soldier from Pennsylvania.
3. Elizabeth Hartsock (1814 - 1892), a pioneer and early settler in Indiana.
4. Henry Hartsock (1843 - 1918), a Union Army soldier during the American Civil War and recipient of the Medal of Honor.
5. Charles Hartsock (1870 - 1941), an American architect known for his work in the Midwestern United States.
While the surname Hartsock originated in England, it has since spread to other parts of the world, particularly through emigration to the Americas and other English-speaking nations.

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

Yes. This page is using the latest surname file currently loaded on Name Census, which is 2020. The historical section above also keeps any older Census surname entries we have for Hartsock (2000, 2010, 2020).
Does the Census include every surname?
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.
Why don't the ancestry percentages always add up to exactly 100%?
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.
