Origin
Meaning and origin of Lennix
The surname LENNIX is of English origin, and its roots can be traced back to the 13th century. The name is believed to have originated from the medieval English personal name Lenn, which was derived from the Old English word "lenn" meaning a pool or stream. The suffix "-ix" was later added, indicating a patronymic form, meaning "son of Lenn."
The earliest recorded instances of the name LENNIX can be found in Yorkshire, England, where it was first documented in the Subsidy Rolls of 1297. The name is also mentioned in the Lay Subsidy Rolls of Buckinghamshire in 1332, suggesting that the LENNIX family had spread to other parts of the country by that time.
In the 14th century, the name appears in various forms, such as Lennox, Lenox, and Lynox, reflecting the variations in spelling and pronunciation during that era. One notable individual from this period was John Lennix, a landowner in Suffolk, who was mentioned in the Court Rolls of 1367.
During the 16th century, the LENNIX name gained prominence with the rise of the Lennox family in Scotland. This clan traced their ancestry to the Earls of Lennox, whose territory was centered around the Loch Lomond area. The name Lennox is believed to be a variant of LENNIX, with the "x" being replaced by an "ox" ending.
In the 17th century, the LENNIX surname was further dispersed throughout England and Scotland. William Lennix, a merchant from Bristol, was recorded in the Chancery Proceedings of 1623. Another notable figure was Robert Lennix, a Scottish soldier who fought in the Wars of the Three Kingdoms during the 1640s.
The 18th century saw the LENNIX name spread to North America, with several immigrants from England and Scotland settling in the American colonies. One of the earliest recorded instances is that of James Lennix, who arrived in Virginia in 1714.
In the 19th century, the LENNIX surname continued to be prominent in various parts of the world. Notable individuals include:
1. Sir John Lennix (1784-1868), a British naval officer who served in the Napoleonic Wars.
2. Margaret Lennix (1819-1901), an Irish-born Australian novelist and poet.
3. William Lennix (1835-1903), a Canadian politician and businessman who served as the Mayor of Toronto.
As the 20th century dawned, the LENNIX name continued to be carried by various individuals, including:
1. Charles Lennix (1890-1977), an American painter and illustrator known for his portraits and landscapes.
2. Eliza Lennix (1915-2004), a British actress and dancer who performed in several West End productions.

The bar chart below shows how Lennix 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 Lennix surname at the time of the 2020 Census, not any inherent property of the name itself.

Does the Census include every surname?

There are two main reasons: rounding and suppression. The Census Bureau rounds published values, and it may suppress very small cells to protect privacy.
