Origin
Meaning and origin of Lewarne
The surname LEWARNE is of Cornish origin, derived from the ancient Cornish place name "Lew Arn" meaning "the place of the iron" or "the place of the iron mines." This name originated in the county of Cornwall, England, during the medieval period when mining for tin and iron ore was a significant industry in the region.
The earliest known recorded use of the surname LEWARNE can be traced back to the 13th century, where it appeared in various spellings such as "Lewarn," "Lewarren," and "Lewarne" in local parish records and land charters. One of the earliest known bearers of the name was John Lewarne, who was recorded as a landowner in the village of Pelynt, Cornwall, in 1297.
In the 16th century, the surname LEWARNE appeared in the Cornish Subsidy Rolls of 1524, which were tax records compiled during the reign of King Henry VIII. This document listed several individuals with the surname, including Raffe Lewarne, Thomas Lewarne, and Jone Lewarne, all residing in different parishes within Cornwall.
During the 17th century, the LEWARNE family established themselves as prominent landowners and miners in the Cornish mining districts. One notable figure from this era was Richard Lewarne (1619-1692), a wealthy mine owner and merchant who served as Mayor of Truro, the county town of Cornwall, in 1670.
Another significant figure bearing the LEWARNE surname was Sir Samuel Lewarne (1701-1779), a successful businessman and Member of Parliament for the borough of Tregony, Cornwall, from 1741 to 1768. He was also a prominent benefactor and contributed to the construction of several churches and public buildings in the county.
In the 19th century, the LEWARNE family continued to play a role in the mining industry and local affairs of Cornwall. One notable individual was John Lewarne (1812-1887), a mine owner and philanthropist who served as High Sheriff of Cornwall in 1870. He was also responsible for establishing several schools and educational institutions in the region.
Other notable individuals with the LEWARNE surname include William Lewarne (1845-1921), a Cornish engineer and inventor who developed several important mining and metallurgical technologies, and Alfred Lewarne (1876-1954), a renowned Cornish artist and painter known for his depictions of the Cornish landscape and mining scenes.

The bar chart below shows how Lewarne 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 Lewarne 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.
