Origin
Meaning and origin of Lusby
The surname Lusby originated in England and dates back to the 12th century. It is believed to be derived from the Old English words "lud" meaning "loud" and "by" meaning "dwelling" or "village". This suggests that the name may have referred to someone who lived in a noisy or loud village.
One of the earliest recorded instances of the name Lusby can be found in the Pipe Rolls of Northamptonshire from 1198, where a Robert de Louseby is mentioned. This spelling variation indicates that the name has evolved over time.
In the Domesday Book of 1086, there is a reference to a place called "Loudebi" in Lincolnshire, which is thought to be the origin of the Lusby surname. This place name likely evolved from the Old English words "hlud" meaning "loud" and "by" meaning "village".
During the 13th century, a family bearing the Lusby name owned lands in the village of Lusby, located in the county of Lincolnshire. This village likely took its name from the family, further cementing the connection between the surname and the geographical area.
One notable individual with the Lusby surname was Sir Thomas Lusby (c. 1430-1492), a English knight and landowner who served as the Sheriff of Lincolnshire in 1476. Another was John Lusby (c. 1570-1642), an English clergyman who served as the rector of Rowston in Lincolnshire.
In the 16th century, a branch of the Lusby family settled in the county of Yorkshire, where they became prominent landowners and gentry. One member of this branch was William Lusby (c. 1580-1644), a Member of Parliament for Aldborough in Yorkshire during the reign of King Charles I.
Moving into the 17th century, another notable Lusby was Sir Peyton Lusby (1638-1688), an English politician and landowner who served as the High Sheriff of Hertfordshire in 1685.
The surname Lusby continued to be found primarily in the counties of Lincolnshire, Yorkshire, and Hertfordshire throughout the 17th and 18th centuries, with various members of the family serving as local gentry, clergymen, and landowners.

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

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 Lusby (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.
