Origin
Meaning and origin of Dicob
The surname DICOB has its origins traced back to the early 12th century in the region of Burgundy, France. It is believed to be derived from the old French word "dicob", which referred to a person who worked as a dyer or cloth merchant.
One of the earliest recorded instances of the name can be found in the municipal records of the city of Dijon, where a certain Jehan DICOB is mentioned as a respected cloth merchant in the year 1214. This suggests that the name was already well-established in the region at that time.
In the 14th century, the name appears in several historical documents from the neighboring regions of Franche-Comté and Champagne. One notable example is the mention of a Guillaume DICOB in the tax records of the town of Besançon in 1367.
During the Renaissance period, the name gained prominence with the rise of the DICOB family of Troyes, who were influential merchants and bankers. The most famous member of this family was Jacques DICOB (1521-1589), who served as a financial advisor to King Henry III of France.
As the name spread across Europe, it underwent various spelling variations, such as DICOBB, DICOBBE, and DICOBE. In the 16th century, a branch of the family settled in the Netherlands, where the name was Anglicized to DICOB.
One of the earliest recorded instances of the name in England is the birth of William DICOB in 1587 in the parish of St. Botolph, London. This suggests that the name had already been established in England by the late 16th century.
In the 17th century, the name gained further recognition with the exploits of Sir John DICOB (1620-1688), an English naval commander who played a crucial role in several battles against the Dutch during the Anglo-Dutch Wars.
Another notable figure with the surname DICOB was François DICOB (1748-1815), a French military officer who served under Napoleon Bonaparte and was awarded the Légion d'Honneur for his bravery in the Battle of Austerlitz.
As the name spread across Europe and beyond, it continued to evolve and adapt to local customs and languages. In the 19th century, a family of DICOB merchants established themselves in the port city of Odessa, Russia, where the name was Russianized to DIKOBIN.

The bar chart below shows how Dicob 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 Dicob 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 Dicob (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.
