Origin
Meaning and origin of Sadigh
The surname "SADIGH" is of Persian origin and can be traced back to the 16th century. It is derived from the Persian word "sadiq," meaning "truthful" or "honest." The name likely originated in the regions of present-day Iran, where Persian was the predominant language.
In the early days, the surname was often spelled as "Sadegh" or "Sadeghi," reflecting the variations in transliteration from Persian to other scripts. Historical records indicate that the name appeared in various Persian manuscripts and documents from the 16th century onwards.
One of the earliest recorded instances of the surname can be found in the "Tadhkirat al-Shu'ara," a biographical anthology of Persian poets written by Dawlat Shah Samarqandi in the 16th century. The book mentions a poet named Mirza Muhammad Sadigh, who lived during the reign of Shah Tahmasp I (1514-1576) of the Safavid dynasty.
The name "SADIGH" also has a connection to the city of Shiraz, located in the southwestern region of Iran. Records from the 17th century mention a prominent family of scholars and poets bearing the surname, with roots in Shiraz.
In the 19th century, Mirza Husayn Khan Sadigh (1823-1896) was a notable Iranian statesman and diplomat who served as the Minister of Foreign Affairs during the Qajar dynasty. He played a crucial role in negotiating treaties and representing Persia in international affairs.
Another notable figure was Sadiq Hidayat (1903-1951), an influential Persian writer and novelist who is considered one of the most renowned figures in modern Persian literature. His works, such as "The Blind Owl" and "Buf-e-Kur" (The Blind Owl), explored themes of existentialism and social criticism.
The surname "SADIGH" can also be found in other parts of the Middle East and Central Asia, where Persian influence and migration patterns have left their mark. For instance, there are records of individuals bearing this surname in regions like Afghanistan, Tajikistan, and parts of the Caucasus region.
Throughout history, the surname "SADIGH" has been associated with individuals from diverse backgrounds, including scholars, poets, statesmen, and literary figures, reflecting the rich cultural heritage of the Persian-speaking world.

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