Origin
The surname Lynum originates from England, specifically the East Midlands region. It is believed to have emerged in the late 12th century, derived from the Old English word "lin" meaning a pool or body of water. The name likely referred to someone who lived near a pool or pond.
The earliest known written record of the name Lynum appears in the Pipe Rolls of Lincolnshire from the year 1195, where it is spelled "Lynholm". This suggests the name may have initially been a locational surname, referring to a place called Linholm or a similar variation.
In the 13th century, the name can be found in various forms such as Lynholm, Lyneholme, and Lynham, reflecting the local dialects and spellings of the time. One notable early bearer of the name was William de Lynholm, who was recorded as a landowner in Nottinghamshire in 1273.
By the 14th century, the spelling had evolved to its modern form of Lynum. A notable example is John Lynum, a merchant from Leicester, who is mentioned in the Borough Records of Leicester in 1347.
Throughout the medieval period, the Lynum family was primarily concentrated in the counties of Leicestershire, Nottinghamshire, and Lincolnshire. Some prominent individuals from this time include:
1. Robert Lynum (c. 1380 - 1446), a wealthy wool merchant and alderman of Leicester.
2. Alice Lynum (c. 1420 - 1498), a landowner and benefactor who endowed a chantry chapel in Nottingham.
3. Thomas Lynum (c. 1510 - 1578), a prominent clergyman and rector of St. Mary's Church in Leicester.
During the 16th and 17th centuries, the Lynum family continued to thrive in the East Midlands region, with many members involved in trades such as farming, weaving, and tanning. Noteworthy individuals from this period include:
4. William Lynum (1567 - 1632), a respected landowner and justice of the peace in Nottinghamshire.
5. Elizabeth Lynum (1601 - 1679), a wealthy widow and philanthropist who donated funds for the construction of a school in Loughborough.
As the centuries progressed, the Lynum family gradually spread across England, with some members even emigrating to the American colonies in the 17th and 18th centuries.
Demographics
Among Census respondents with the surname Lynum, the largest self-reported group is Black at 58.1%. The next largest groups are White (29.5%) and Two or More Races (6.8%).
The bar chart below shows how Lynum 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 Lynum 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.
