Origin
The surname OKEEFFE is of Irish origin, with its roots dating back to the ancient Gaelic Ó Caoimh clan in County Cork, Ireland. The name is derived from the Gaelic words "caomh," meaning "gentle" or "kind," and "ó," signifying "descendant of."
The OKEEFFE name can be traced back to the 11th century, when it was first recorded in the Annals of Innisfallen, a chronicle of medieval Irish history. The name was prominent among the ruling families of the Uí Ímhair and Uí Laoghaire dynasties in the region of West Munster.
One of the earliest known references to the OKEEFFE surname can be found in the Pipe Rolls of Cloyne, a taxation record from 1285, where the name appears as "O'Kyfy." Over the centuries, various spellings emerged, including O'Keyffe, O'Keefe, and the modern OKEEFFE.
In the 16th century, the OKEEFFE clan played a significant role in the Desmond Rebellions against English rule in Ireland. One notable figure was Piers OKEEFFE, a military leader who fought alongside the Earl of Desmond in the Second Desmond Rebellion (1579-1583).
Another prominent individual was John OKEEFFE (1747-1833), an Irish playwright and satirist known for his comedies and farces. His most famous work, "The Agreeable Surprise," premiered in 1781 and enjoyed widespread popularity.
In the realm of art, Georgia OKEEFFE (1887-1986) remains one of the most celebrated American artists of the 20th century. She was a pioneering figure in the field of modern art, renowned for her distinctive paintings of natural forms and landscapes.
Another notable OKEEFFE was Patrick OKEEFFE (1827-1913), an Irish-born prelate who served as the second Bishop of Hartford, Connecticut, from 1888 to 1899. He played a crucial role in the growth and development of the Catholic Church in New England during his episcopacy.
The OKEEFFE name has also been associated with various place names in Ireland, such as Kilcaskan Castle, an ancient fortress located in County Cork, which was once the seat of the OKEEFFE clan.
Demographics
Among Census respondents with the surname Okeeffe, the largest self-reported group is White at 91.4%. The next largest groups are Hispanic (4.9%) and Two or More Races (1.8%).
The bar chart below shows how Okeeffe 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 Okeeffe 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 Okeeffe (2000, 2010, 2020).
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.
