Origin
The surname Dunham has its origins in England, dating back to the medieval period. It is believed to have originated from a place name, derived from the Old English words "dun" meaning hill or down, and "ham" meaning homestead or village. This suggests that the name may have referred to someone who lived in a homestead situated on or near a hill.
One of the earliest recorded instances of the name can be found in the Domesday Book of 1086, where it appears as "Dunham" in various counties across England, such as Norfolk, Essex, and Buckinghamshire. This indicates that the name was already well-established by the time of the Norman Conquest.
In the 13th century, the name appeared in various forms, including "Doneham," "Dunham," and "Dunnam," reflecting the variations in spelling that were common during that period. Records from this time show individuals bearing the name Dunham living in various parts of England, particularly in the counties of Essex, Suffolk, and Norfolk.
One notable historical figure with the surname Dunham was John Dunham, born around 1589 in Leiden, Netherlands. He was one of the early Puritan settlers of the Plymouth Colony in Massachusetts, arriving on the ship Mayflower in 1620. His descendants went on to become prominent figures in American history.
Another significant individual was Josiah Dunham, born in 1692 in Woodbridge, New Jersey. He was a renowned clockmaker and silversmith, known for his intricate and highly sought-after works of art. His clocks and silverware are now considered valuable antiques and can be found in various museums and private collections.
In the literary world, the name is associated with Samuel Astley Dunham, born in 1800 in England. He was a prolific writer and editor, known for his works on history, literature, and travel. One of his most notable publications was "The History of Spain and Portugal," a comprehensive account of the Iberian Peninsula.
The name Dunham has also been linked to several notable military figures. One such individual was Cyrus Dunham, born in 1779 in Connecticut. He served as a brigadier general in the United States Army during the War of 1812 and played a crucial role in the defense of Fort Erie.
Another noteworthy bearer of the surname was Mary Dunham, born in 1890 in New York. She was a pioneering aviator and one of the first women to obtain a pilot's license in the United States. Her achievements paved the way for many women in the field of aviation.
Demographics
Among Census respondents with the surname Dunham, the largest self-reported group is White at 81.9%. The next largest groups are Black (9.8%) and Two or More Races (4.0%).
The bar chart below shows how Dunham 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 Dunham 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.
