Origin
The surname ODONAL has its origins in Ireland, with the first recorded instances dating back to the 9th century AD. It is believed to be derived from the Gaelic words "O'Domhnaill," which translate to "descendant of Domhnall," a personal name that means "world ruler" or "world mighty."
During the medieval period, the name was primarily associated with the O'Donnell clan, a powerful family from County Donegal in Ulster Province, Ireland. The O'Donnells were renowned for their military prowess and played a significant role in Irish history, particularly during the Irish Confederate Wars of the 17th century.
One of the earliest recorded instances of the name ODONAL can be found in the Annals of Ulster, a chronicle of medieval Irish history. The annals mention Áed Ua Domnaill, King of Ailech, who ruled in the late 8th century. Additionally, the name appears in the Book of Leinster, a 12th-century manuscript containing various Irish texts and genealogies.
In the 14th century, Niall Óg Ó Domhnaill, born around 1290, was a notable figure who served as the King of Tír Chonaill (County Donegal) and played a significant role in the Irish Bruce Wars against the English. Another prominent bearer of the name was Calvagh O'Donnell (c. 1510-1555), who was the last inaugurated Chief of the O'Donnell clan and a key figure in the Nine Years' War against English rule.
Other notable individuals with the surname ODONAL include Hugh Roe O'Donnell (c. 1572-1602), an Irish chieftain and one of the leaders of the Irish forces during the Nine Years' War, and Red Hugh O'Donnell (1572-1602), his brother and a renowned military commander who fought against English colonization efforts in Ireland.
Over time, the surname ODONAL has undergone various spelling variations, such as O'Donnell, O'Donell, and O'Donal, reflecting regional dialects and anglicization. While the name retains its strongest roots in Ireland, particularly in Ulster and County Donegal, it has since spread to other parts of the world through Irish emigration.
Demographics
Among Census respondents with the surname Odonal, the largest self-reported group is White at 89.9%. The next largest groups are Black (6.4%) and Two or More Races (2.8%).
The bar chart below shows how Odonal 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 Odonal 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. 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.
