Origin
The surname APTHORPE is believed to have originated in England, specifically in the county of Northamptonshire, during the medieval period. It is derived from the Old English words "aeppel" (apple) and "thorpe" (village or hamlet), suggesting that the name may have originally referred to a village or settlement where apple orchards were prominent.
The earliest known recorded instances of the name APTHORPE can be found in various historical records from the 13th and 14th centuries. One notable reference is in the Hundred Rolls of Northamptonshire, a census-like document compiled in 1273, which lists individuals with the surname APTHORPE residing in the village of Apthorp (now known as Apethorpe).
In the 15th century, the APTHORPE family gained prominence in Northamptonshire, with several members holding positions of influence and power. Sir John APTHORPE (c. 1455-1529) was a respected landowner and member of the gentry, serving as a Member of Parliament for Northamptonshire during the reign of Henry VIII.
Another notable figure was Sir William APTHORPE (c. 1600-1675), a successful merchant and alderman in the City of London. He played a significant role in the East India Company and was knighted by King Charles II in recognition of his contributions.
During the English Civil War, Captain Richard APTHORPE (c. 1620-1680) was a Royalist officer who fought alongside King Charles I's forces. After the war, he was granted lands in Ireland as part of the Settlement of Ireland.
In the 18th century, the APTHORPE family continued to hold influential positions, with Sir East APTHORPE (1713-1781) serving as a Member of Parliament for Grantham and later becoming Lord Mayor of London in 1767.
The surname APTHORPE also has connections to the United States, with John APTHORPE (1744-1809) being a prominent merchant and landowner in Massachusetts during the American Revolutionary War era. He was a loyalist to the British Crown and was forced to flee to England during the conflict.
While the name APTHORPE is not as common today as it once was, it remains a part of the rich tapestry of English surnames, with its origins rooted in the medieval villages of Northamptonshire and a history that spans centuries of notable individuals and events.
Demographics
Among Census respondents with the surname Apthorpe, the largest self-reported group is White at 95.0%. The next largest groups are Two or More Races (3.0%) and Hispanic (2.0%).
The bar chart below shows how Apthorpe 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 Apthorpe 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.
