Origin
The surname Gilpatrick has its origins in Ireland, emerging during the Middle Ages. It derives from the Gaelic personal name "Giolla Phádraig," which translates to "servant of Patrick." This name was likely adopted by those who revered St. Patrick, the patron saint of Ireland, or those who lived near a church dedicated to him.
One of the earliest recorded instances of the name can be found in the Annals of Ulster, a chronicle of medieval Irish history. In 1276, the name "Gilla Patraic" is mentioned, referring to an individual who held a prominent position within the Gaelic nobility.
The Gilpatrick surname has undergone various spelling variations throughout history, including Gilpatrick, Gilpatric, Gilpatridge, and Kilpatrick. These variations often reflect regional dialects or variations in spelling conventions over time.
In the 16th century, the name Gilpatrick appeared in the Fiants of the Tudor Sovereigns, a collection of official records from the reign of the Tudor monarchs in England and Ireland. This suggests that individuals bearing this surname held positions of significance during that period.
Notable individuals with the surname Gilpatrick include:
1. John Gilpatrick (c. 1610-1675), an Irish physician and astrologer who served as the personal physician to King Charles I of England.
2. Thomas Gilpatrick (1739-1816), an Irish-born American soldier who fought in the American Revolutionary War and later served as a member of the Virginia House of Delegates.
3. Jane Gilpatrick (1791-1862), a Scottish-born American author and educator who founded one of the first female academies in the United States.
4. William Gilpatrick (1817-1892), an Irish-born architect and engineer who designed several prominent buildings in New York City, including the St. Patrick's Cathedral.
5. James Gilpatrick (1869-1944), an Irish-American businessman and philanthropist who founded the Gilpatrick Construction Company and was instrumental in developing infrastructure in the American West.
While the surname Gilpatrick has its roots in Ireland, it has since spread to various parts of the world due to emigration and migration patterns. However, its origins can be traced back to the Gaelic tradition and the reverence for St. Patrick in medieval Ireland.
Demographics
Among Census respondents with the surname Gilpatrick, the largest self-reported group is White at 89.8%. The next largest groups are Hispanic (5.2%) and Two or More Races (3.0%).
The bar chart below shows how Gilpatrick 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 Gilpatrick 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 Gilpatrick (2000, 2010, 2020).
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.
