Origin
Meaning and origin of Lasman
The surname Lasman originated in England during the medieval period. It is believed to have derived from the Old English words "laes" meaning pasture or meadow, and "mann" meaning man or person. This suggests that the name may have originally referred to someone who lived near or tended to a pasture or meadow.
One of the earliest recorded instances of the surname Lasman can be found in the Domesday Book of 1086, which was a comprehensive record of landowners and their properties in England commissioned by William the Conqueror. The name appears as "Laesmanne" in this document, further supporting its Old English origins.
In the 13th century, the surname was found in various spellings such as "Laseman," "Lasseman," and "Lesmane" in records from various counties in England, including Essex, Lincolnshire, and Yorkshire. This indicates that the name had spread across different regions of the country by this time.
One notable bearer of the Lasman surname was Sir John Lasman, a prominent landowner and knight who lived in the 14th century. He is mentioned in several historical documents from the reign of Edward III, including records of land grants and military service.
Another individual of note was William Lasman, born in 1542 in Gloucestershire, England. He was a respected scholar and theologian who attended Oxford University and later became a vicar in the Church of England.
In the 17th century, the surname Lasman is found in the records of the Massachusetts Bay Colony in America, suggesting that some individuals bearing this name were among the early English settlers in the New World.
A notable American bearer of the Lasman surname was Samuel Lasman, born in 1784 in Pennsylvania. He was a successful merchant and businessman who played a prominent role in the development of the city of Pittsburgh.
Other historical figures with the surname Lasman include Robert Lasman, a 19th-century English painter known for his landscape and portraiture works, and Elizabeth Lasman, a 20th-century British author and poet whose works explored themes of nature and spirituality.

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

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.

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