Origin
Meaning and origin of Byrom
The surname BYROM originated from England in the 13th century. It is believed to have derived from the Old English words "byr" meaning cottage or dwelling, and "holme" meaning a small island or dry ground in a marshy area. This suggests that the name may have initially referred to someone who lived in a cottage on a small island or raised land in a wetland region.
One of the earliest recorded mentions of the surname BYROM can be found in the Pipe Rolls of Lancashire from 1246, where a person named Robert de Byrom is listed. This indicates that the name was already established in that region during the medieval period.
The name BYROM is also found in the Domesday Book of 1086, which was a comprehensive record of landholders and properties in England commissioned by William the Conqueror. This further solidifies the ancient roots of the surname in the country.
In the 16th century, a notable figure bearing the name BYROM was John Byrom (1692-1763), an English poet, inventor, and writer. He is best known for creating a system of shorthand writing and for his literary works, including pastoral poems and religious pieces.
Another prominent individual with the surname BYROM was Edward Byrom (1566-1628), an English Catholic priest and martyr. He was executed for his involvement in the Gunpowder Plot, a failed attempt to assassinate King James I of England in 1605.
In the 18th century, John Byrom (1770-1834) was an English architect and surveyor who designed several notable buildings in Manchester, including the Royal Infirmary and the Bridgewater House.
The surname BYROM can also be traced back to various place names in England, such as Byrom in Lancashire and Byrom Hall in Cheshire. These locations likely derived their names from the same Old English roots as the surname itself.
Throughout history, the surname BYROM has been spelled in various ways, including Birom, Byrome, and Byram, reflecting the evolution of language and regional variations in pronunciation and spelling.

The bar chart below shows how Byrom 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 Byrom 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 Byrom (2000, 2010, 2020).
Does the Census include every surname?
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.
Why don't the ancestry percentages always add up to exactly 100%?
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.
