Origin
The surname SWALLOM is believed to have originated in England during the medieval period. It is thought to be derived from the Old English word "swallow," referring to the small migratory bird. This suggests that the name may have initially been a nickname for someone who had a particular affinity or resemblance to the swallow.
One of the earliest recorded instances of the SWALLOM name can be found in the Domesday Book of 1086, which was a comprehensive survey of land ownership in England commissioned by William the Conqueror. The entry mentions a landowner named Swallom in the county of Lincolnshire.
In the 13th century, variations of the name, such as Swalowe and Swalewe, appeared in various historical records across different regions of England. These variations likely reflect the evolving spelling and pronunciation of the name over time.
One notable early bearer of the SWALLOM name was Sir John Swallom, a knight who fought in the Wars of the Roses during the 15th century. He was known for his bravery and loyalty to the House of Lancaster.
Another prominent figure was William Swallom, born in 1562 in Oxfordshire. He was a renowned scholar and author who wrote extensively on subjects such as philosophy and theology. His works were widely read and influential during the Elizabethan era.
In the 17th century, the SWALLOM name was associated with the town of Swallowfield in Berkshire. This place name is believed to have influenced the spelling and pronunciation of the surname in that region.
During the 18th century, a notable bearer of the SWALLOM name was Elizabeth Swallom (1720-1798), a successful businesswoman who owned and operated a tavern in London. She was known for her entrepreneurial spirit and was a respected figure in her community.
Another significant figure was John Swallom (1776-1856), a prominent architect who designed several notable buildings in London, including the Royal Opera House. His works were widely admired for their elegant and innovative designs.
While the surname SWALLOM is not as common today as it once was, it has a rich history that spans centuries and reflects the diverse experiences and accomplishments of those who bore this name throughout England's past.
Demographics
Among Census respondents with the surname Swallom, the largest self-reported group is White at 95.3%. The next largest groups are American Indian/Alaska Native (2.8%) and Hispanic (1.9%).
The bar chart below shows how Swallom 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 Swallom 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.
