Origin
The surname Jeffreys originates from England, and it is believed to have emerged during the medieval period. The name is derived from the given name Jeffrey, which is an anglicized version of the Old French name Geoffroi, itself derived from the Germanic name Godafrid, meaning "peace of God."
The earliest recorded instance of the surname Jeffreys can be traced back to the 13th century. In the Hundred Rolls of Oxfordshire from 1273, there is a reference to a man named Geffrey de la Hethe. This suggests that the surname was initially used as a descriptive name, indicating a person's place of origin or residence.
The Jeffreys surname has been associated with several notable individuals throughout history. One of the earliest and most prominent figures bearing this name was Sir George Jeffreys (1645-1689), an English judge infamous for his brutality during the Bloody Assizes. He gained notoriety for his harsh sentences against those involved in the Monmouth Rebellion of 1685.
Another notable bearer of the Jeffreys surname was John Jeffreys (1609-1677), a Welsh-born judge and politician who served as Chief Justice of the Carmarthen Circuit in Wales. He was also a member of the Long Parliament during the English Civil War.
In the realm of literature, the surname Jeffreys is associated with Richard Jefferies (1848-1887), a renowned English nature writer and novelist. His works, such as "Bevis: The Story of a Boy" and "The Story of My Heart," celebrated the beauty of the English countryside and explored themes of naturalism and spirituality.
During the 18th century, George Jeffreys (1678-1755), an English writer and scholar, gained recognition for his contributions to literary criticism and his work as a translator of classical texts. He is particularly known for his editions of the works of Edmund Spenser and William Shakespeare.
Another notable figure with the Jeffreys surname is John Jeffreys (1744-1819), a British Naval officer who served during the American Revolutionary War and the French Revolutionary Wars. He rose to the rank of Vice Admiral and played a significant role in several naval engagements.
Demographics
Among Census respondents with the surname Jeffreys, the largest self-reported group is White at 70.9%. The next largest groups are Black (19.2%) and Two or More Races (5.9%).
The bar chart below shows how Jeffreys 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 Jeffreys 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.
