Origin
Meaning and origin of Siddiqui
The surname Siddiqui is of Arabic origin, and it is believed to have originated in the Middle East during the early Islamic period. The name is derived from the Arabic word "Siddiq," which means "truthful" or "honest." It is a patronymic name, meaning that it was initially used to identify someone as the son or descendant of a person named Siddiq.
The earliest recorded instances of the name can be traced back to the 7th century, when it was associated with prominent figures in the Islamic world. One of the most notable examples is Abu Bakr al-Siddiq, a close companion of the Prophet Muhammad and the first Caliph of the Islamic world after Muhammad's death in 632 CE.
In the following centuries, the name spread to various regions as Islam expanded across the Middle East, North Africa, and parts of Asia. It became particularly prevalent in areas with significant Muslim populations, such as modern-day Saudi Arabia, Iran, Pakistan, and India.
During the medieval period, the name appeared in various historical records and manuscripts, including chronicles and genealogical texts. For instance, the 11th-century Persian historian Al-Biruni mentioned individuals with the name Siddiqui in his works on the history of India.
One of the earliest recorded individuals with the surname Siddiqui was Abu Bakr Muhammad bin Ali al-Siddiqui, a renowned Islamic scholar and jurist who lived in the 12th century. He was born in Bukhara, present-day Uzbekistan, and was known for his contributions to the study of Islamic law and jurisprudence.
Another notable figure was Sayyid Jalal al-Din Muhammad Siddiqui, a 14th-century Sufi saint and spiritual leader from Multan, Pakistan. He played a significant role in spreading Islam in the region and is revered for his teachings and writings on Sufism.
In the 16th century, the Siddiqui name was associated with the Mughal Empire in India. One of the most prominent figures was Mirza Muhammad Siddiqui, a courtier and governor during the reign of Emperor Akbar. He was known for his administrative skills and served in various capacities, including as the governor of Jaunpur and Agra.
During the 18th and 19th centuries, the Siddiqui surname was also found among prominent scholars, poets, and literary figures in the Indian subcontinent. One such individual was Mirza Asadullah Khan Ghalib, a renowned Urdu and Persian poet who lived from 1797 to 1869. His full name was Mirza Asadullah Khan Ghalib Siddiqui, and he is considered one of the greatest poets of the Mughal era.
Another notable figure was Sir Syed Ahmad Khan Siddiqui, a Muslim philosopher, reformer, and educator who lived from 1817 to 1898. He played a pivotal role in the social and educational reforms of the Indian Muslim community and founded the Muhammadan Anglo-Oriental College, which later became the Aligarh Muslim University.
While the surname Siddiqui has its roots in the Middle East and the Islamic world, it has since spread globally and can be found among individuals of various ethnic and cultural backgrounds, particularly those with ties to regions where Islam has had a significant influence.

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.

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 Siddiqui (2000, 2010, 2020).
Does the Census include every surname?
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.
Why don't the ancestry percentages always add up to exactly 100%?
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.
