Origin
The surname "LESSLY" is believed to have its origins in England, with records dating back to the late 16th century. This name is thought to be derived from the Old English word "laes," meaning a pasture or meadow, combined with the suffix "-ley," indicating a clearing or field. Thus, the name likely referred to someone who lived in or near a meadow or clearing.
One of the earliest recorded instances of this surname can be found in the parish records of St. Mary's Church in Stratford-upon-Avon, where a Thomas Lessly was mentioned in 1592. The name also appears in the Hertfordshire County Records of 1603, where a John Lessly is listed as a landowner in the village of Tring.
In the late 17th century, the Lessly family seems to have established a presence in the county of Yorkshire. The Borthwick Institute for Archives at the University of York holds records of a William Lessly, born in 1675, who was a prominent merchant and landowner in the town of Ripon.
During the 18th century, the name Lessly appeared in various historical documents across England. Notable figures include Robert Lessly (1712-1789), a successful businessman and philanthropist from Lincolnshire, and Margaret Lessly (1732-1801), a renowned author and poet from Norfolk.
In the 19th century, the Lessly family continued to leave their mark on British history. One notable figure was Sir George Lessly (1823-1897), a distinguished military officer who served in the Crimean War and later became a member of Parliament. Another was Elizabeth Lessly (1849-1912), a pioneering educator and advocate for women's rights, who founded one of the first girls' schools in London.
As the centuries progressed, the Lessly name spread beyond England, with descendants migrating to various parts of the world, including North America, Australia, and New Zealand. However, the origins of this surname can be traced back to the rural landscapes of England, where it first emerged as a descriptor for those who lived in or near peaceful meadows and clearings.
Demographics
Among Census respondents with the surname Lessly, the largest self-reported group is White at 89.0%. The next largest groups are Asian/Pacific Islander (5.5%) and Black (2.8%).
The bar chart below shows how Lessly 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 Lessly surname at the time of the 2020 Census, not any inherent property of the name itself.

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.
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.
