Origin
Meaning and origin of Dooman
The surname Dooman is of English origin and is believed to have originated in the region of Dorset, England during the late medieval period. The name is thought to be derived from the Old English word "dumn," meaning "valley" or "deep gulley." This suggests that the earliest bearers of the name may have resided in or near a valley or gulley.
One of the earliest recorded instances of the name Dooman can be found in the Pipe Rolls of Dorset, dated 1242. This ancient record lists a individual named Richard de Duman, indicating that the name was present in the region at that time. The spelling variation "Duman" is likely an earlier form of the modern surname Dooman.
In the 14th century, the name appeared in various manorial records and tax rolls in the counties of Dorset and Somerset. For example, the Lay Subsidy Rolls of 1332 list a William Doman residing in the village of Bridport, Dorset. This suggests that the name had spread to neighboring counties by that point.
The Dooman surname is also found in the Hertfordshire Subsidy Rolls of 1381, which record a Thomas Doman residing in the town of Watford. This indicates that the name had become more widely distributed across England by the late 14th century.
Notable individuals with the surname Dooman throughout history include:
1. John Dooman (c. 1570 - 1625), an English merchant and explorer who traveled to the East Indies and wrote accounts of his voyages.
2. Sarah Dooman (1730 - 1805), a British author and poet known for her works on nature and rural life.
3. William Dooman (1772 - 1858), a Scottish politician and landowner who served as a member of parliament for the county of Kinross.
4. James Dooman (1818 - 1891), an English architect who designed several notable churches and public buildings in London and the surrounding areas.
5. Margaret Dooman (1865 - 1932), an American educator and suffragist who campaigned for women's rights and the establishment of equal educational opportunities.
While the Dooman surname is not among the most common in English-speaking countries today, its history can be traced back to the medieval period in the English county of Dorset, where it likely originated from a place name or geographical feature.
Demographics
Ancestry and ethnicity for Dooman

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

Does the Census include every surname?

There are two main reasons: rounding and suppression. The Census Bureau rounds published values, and it may suppress very small cells to protect privacy.
