Origin
Meaning and origin of Lamborn
The surname Lamborn is believed to have originated in England, with its roots dating back to the medieval period. It is a locational surname, derived from the Old English words "lamb" and "burna," which together mean "a stream where lambs drank." This suggests that the name was likely associated with a particular place where sheep were raised or grazed near a stream or water source.
The earliest recorded instances of the name Lamborn can be traced back to the 13th century, with various spellings such as Lamberne, Lambourne, and Lamborne appearing in historical records. One notable example is found in the Pipe Rolls of Berkshire from 1242, where a Robert de Lamborne is mentioned.
During the 14th century, the name Lamborn appeared in several historical documents, including the Subsidy Rolls of Worcestershire in 1327, which listed a John de Lamborne. Additionally, the Feet of Fines for Essex in 1377 recorded a Thomas Lambrun, which is likely a variation of the same name.
In the 16th century, the name Lamborn was associated with several individuals of note. One such person was John Lamborn, a prominent merchant and alderman in the city of Bristol, who lived from around 1510 to 1580. Another was Thomas Lamborn, a clergyman who served as the Rector of Westwell in Kent from 1553 until his death in 1600.
The 17th century saw the emergence of William Lamborn, a noted English writer and playwright who was born in 1615 and died in 1676. His most famous work was a play titled "The Converted Courtezan," which was published in 1640.
In the 18th century, the name Lamborn was associated with several notable figures, including John Lamborn (1693-1761), a wealthy merchant and landowner in Leicestershire, and Samuel Lamborn (1720-1789), a renowned clockmaker based in London.
The 19th century brought forth James Lamborn (1810-1876), a prominent English architect who was responsible for designing several notable buildings in London, including the Church of St. Peter's in Bethnal Green and the Fishmongers' Hall on London Bridge.
Throughout its history, the surname Lamborn has been linked to various place names and locations within England, such as Lambourn in Berkshire, Lamborne in Essex, and Lambourne in Worcestershire, further reinforcing its locational origins.

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.

Keep in mind that these are self-reported numbers.
