Origin
The surname THURLOW originated in England, deriving from the Old English words "þurru" meaning "dry" and "hlaw" meaning "hill" or "mound". It is believed to have been initially used as a topographic name for someone who lived on or near a dry hill or elevated ground.
The earliest recorded instance of the name dates back to the Domesday Book of 1086, where it appears as "Turlau" in Suffolk. This spelling variation highlights the evolution of the name over time.
In the late 12th century, the name was documented as "Thurlow" in the Pipe Rolls of Norfolk, indicating its association with the village of Thurlow in Suffolk. This village likely derived its name from the same Old English roots as the surname.
One of the earliest known bearers of the name was Roger de Thurlow, mentioned in the Curia Regis Rolls of Hertfordshire in 1201. Another notable figure was John Thurlow, who served as a Member of Parliament for Suffolk in 1382.
During the 16th century, the surname THURLOW gained prominence with Edward Thurlow (1531-1595), an English merchant and member of the Company of Merchant Adventurers. His grandson, Edward Thurlow (1616-1683), was a prominent lawyer and served as Lord Chancellor of England from 1778 to 1792.
Another significant individual with this surname was Thomas Thurlow (1737-1811), who served as Bishop of Lincoln from 1779 to 1787 and later as Bishop of Durham until his death in 1811.
In the literary world, Edward Hovel Thurlow (1781-1829) was an English poet and author, known for his works such as "The Wandering Jew" and "The Fairy Favour".
The THURLOW surname has also been associated with notable military figures, such as Sir Edward Thurlow (1814-1890), a British Army officer who served in the Crimean War and was awarded the Victoria Cross for his bravery.
Demographics
Among Census respondents with the surname Thurlow, the largest self-reported group is White at 93.1%. The next largest groups are Two or More Races (2.8%) and Hispanic (2.3%).
The bar chart below shows how Thurlow 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 Thurlow 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.
