Origin
Meaning and origin of Ullom
The surname ULLOM is believed to have originated in England during the medieval period. It is thought to be derived from the Old English word "ulm," which referred to an elm tree. This suggests that the name may have initially referred to someone who lived near a prominent elm tree or a place where elm trees were abundant.
One of the earliest recorded instances of the surname ULLOM can be found in the Domesday Book of 1086, which was a comprehensive survey of landholdings in England commissioned by William the Conqueror. The name appears in various spellings, such as "Ulmo" and "Ulmere," indicating its connection to the Old English word for elm.
During the 13th century, the surname ULLOM began to appear in various historical records, such as the Hundred Rolls of 1273, which listed landholders and their properties. One notable individual from this time was John Ullom, who was mentioned in the records of Oxfordshire in 1279.
In the 14th century, the surname ULLOM continued to be documented in various parts of England. One example is Robert Ullom, a merchant from Yorkshire who was recorded in the records of the city of York in 1352.
As the centuries passed, the spelling of the surname evolved, with variations such as "Ullum" and "Oulom" appearing in historical records. One notable individual from the 16th century was Thomas Ullom, who was born in 1532 and served as a parish priest in Gloucestershire.
During the 17th century, the surname ULLOM spread beyond England, with some bearers of the name emigrating to the American colonies. One such individual was William Ullom, who was born in 1642 in Lincolnshire and later settled in Virginia.
In the 18th century, the surname ULLOM continued to be present in both England and the American colonies. Notable individuals from this time include John Ullom, who was born in 1712 in Northamptonshire, and Samuel Ullom, who was born in 1765 in Pennsylvania.
Throughout the 19th century, the surname ULLOM remained relatively uncommon but continued to be documented in various parts of the English-speaking world. One notable bearer of the name was Charles Ullom, an English artist who was born in 1822 and became known for his landscape paintings.

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 Ullom surname at the time of the 2020 Census, not any inherent property of the name itself.

Is this page using the latest Census data?
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 Ullom (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.
