Origin
The surname Larimore is of English origin, with its roots traced back to the late 16th century. It is believed to have originated from the place name "Larmor" in the county of Lancashire, England. This place name is derived from the Old English words "ler" meaning a place of learning or instruction and "mor" meaning a marsh or moor.
The earliest recorded instances of the name Larimore can be found in parish records and tax rolls from the late 1500s and early 1600s in the Lancashire area. The name was likely first adopted as a surname by families residing in or near the settlement of Larmor.
One of the earliest known individuals with the surname Larimore was John Larimore, born around 1610 in Lancashire. Records show he was a landowner and farmer in the village of Larmor.
In the 17th century, the Larimore surname began to spread beyond Lancashire as families migrated to other parts of England and eventually to the American colonies. One notable early American with this surname was William Larimore, born in 1652 in Gloucestershire, England. He immigrated to Virginia in the late 1600s and became a prosperous landowner and prominent figure in the colony.
Another significant figure in the history of the Larimore name was Elizabeth Larimore, born in 1742 in Pennsylvania. She was a prominent Quaker and played an active role in the abolitionist movement, advocating for the end of slavery in the United States.
In the 19th century, the Larimore surname gained prominence in the American Midwest. One notable individual was Joseph Larimore, born in 1810 in Ohio. He was a successful businessman and landowner, and the town of Larimore, North Dakota, was named after him when it was founded in 1881.
Other notable individuals with the Larimore surname include Charles Larimore, a prominent educator and university president born in 1835 in Indiana, and Mary Larimore, born in 1876 in Illinois, who was a pioneering female physician and advocate for women's health.
Demographics
Among Census respondents with the surname Larimore, the largest self-reported group is White at 91.3%. The next largest groups are Two or More Races (3.8%) and Hispanic (2.7%).
The bar chart below shows how Larimore 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 Larimore 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.
