Meaning & origin

Siaosi is a Polynesian adaptation of George, a name that has traveled widely from its Greek origins. In the United States, Siaosi has been recorded since 1980, but its usage has been relatively rare, never reaching high ranks. The name saw its peak in 2015 at rank 9,714, though its trajectory has been generally falling since 2014. With an incidence of 1 in 244,011 in 2025, Siaosi remains a distinctive choice, primarily used within Tongan and Samoan families. The name reflects both cultural heritage and a global Christian tradition, offering a unique alternative to the more common George.

Siaosi is the Tongan and Samoan form of George, which derives from the Greek name Georgios, meaning 'farmer' or 'earth-worker', and ultimately from georgos 'earthworker'. The name George was adopted into Christian tradition through Saint George, and spread via colonialism and missionary activity to Polynesia, where it was adapted as Siaosi. In Tonga and Samoa, Siaosi has been used since the 19th century, particularly among Christian families.
