Origin
The surname Mallory originated in Normandy, a region in northern France, during the medieval period. It is derived from the Old French words "mal" meaning "ill" and "orie" meaning "fortune," together meaning "unlucky" or "unfortunate." The name may have been given as a nickname to someone who was considered unlucky or who had experienced misfortune.
The Mallory surname first appeared in England after the Norman Conquest of 1066. It was likely brought to England by Norman settlers and knights who accompanied William the Conqueror. One of the earliest recorded instances of the name is in the Domesday Book of 1086, which was a survey of landowners commissioned by William the Conqueror.
In the 12th century, the name appears in the records of the Knights Templar, a prominent Catholic military order during the Crusades. Sir Robert Mallory was a notable Knight Templar who participated in the Third Crusade in the late 12th century.
During the 13th century, the Mallory surname was associated with the village of Mallory in Yorkshire, England. It is believed that the name may have derived from this place name, which was originally spelled "Malorie" or "Malore."
One of the earliest notable figures with the Mallory surname was Sir John Mallory, who lived in the late 14th century and served as a Member of Parliament for Northamptonshire in 1379. Another prominent individual was Sir Thomas Mallory, a 15th-century English writer best known for compiling the legendary tales of King Arthur into the famous work "Le Morte d'Arthur," published in 1485.
In the 16th century, the Mallory family established themselves as landowners and gentry in various parts of England, particularly in Lincolnshire, Derbyshire, and Yorkshire. Sir Christopher Mallory, born in 1492, was a Member of Parliament for Ripon and held estates in Yorkshire.
During the English Civil War in the 17th century, the Mallory family aligned themselves with the Royalist cause, supporting King Charles I. Sir John Mallory, born in 1610, was a Royalist commander who fought against the Parliamentarians and was eventually captured and imprisoned.
Other notable figures with the Mallory surname include George Mallory, a famous English mountaineer who participated in the first three British expeditions to Mount Everest in the early 20th century and may have been the first person to reach the summit in 1924, before tragically dying on the descent.
Demographics
Among Census respondents with the surname Mallory, the largest self-reported group is White at 60.2%. The next largest groups are Black (30.7%) and Two or More Races (4.7%).
The bar chart below shows how Mallory 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 Mallory 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 Mallory (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.
