Origin
Meaning and origin of Tuiono
The surname TUIONO is believed to have originated in the Samoan Islands, located in the South Pacific Ocean. It is a name that can be traced back to the late 18th century, with its roots stemming from the ancient Samoan language.
The name TUIONO is derived from the Samoan word "tui," which means "ruler" or "chief," and "ono," meaning "six." This combination suggests that the name may have been initially bestowed upon a prominent leader or chieftain who held authority over six villages or territories.
Historical records indicate that the TUIONO surname first appeared in the oral traditions and genealogical accounts of various Samoan families. These accounts were meticulously preserved and passed down through generations, serving as a testament to the significance of this name in Samoan heritage.
One of the earliest documented references to the TUIONO surname can be found in the writings of John Williams, a British missionary who arrived in Samoa in the 1830s. In his journals, Williams mentions the name TUIONO in connection with a respected village chief he encountered during his travels.
Notable individuals who have carried the TUIONO surname throughout history include:
1. Tuiono Nanai (c. 1790 - 1865), a revered Samoan orator and storyteller renowned for his mastery of the Samoan language and oral traditions.
2. Tuiono Viliamu (1825 - 1892), a prominent Samoan chief who played a crucial role in negotiating peace treaties between rival villages during a period of inter-village conflicts.
3. Tuiono Saga (1867 - 1941), a celebrated Samoan navigator and wayfinder who guided voyaging canoes across vast stretches of the Pacific Ocean using traditional celestial navigation techniques.
4. Tuiono Meleisea (1902 - 1978), a respected Samoan scholar and educator who dedicated his life to preserving and promoting Samoan language, culture, and history.
5. Tuiono Tofiga (1935 - 2011), a renowned Samoan artist and woodcarver whose intricate works depicting traditional Samoan motifs and symbols gained international recognition.
While the TUIONO surname may not have been as widely documented in historical records as some other Samoan names, its presence in oral traditions and genealogical accounts attests to its deep-rooted significance within the Samoan cultural heritage.

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