Origin
The surname ACHORN is believed to have originated in England during the medieval period, likely derived from a place name or a descriptive word related to an oak tree or a valley. One of the earliest recorded instances of the name can be found in the Domesday Book of 1086, which was a comprehensive survey of landowners and properties commissioned by William the Conqueror after the Norman conquest of England.
During the 13th century, variations of the name such as "Acorne" and "Akehorne" appeared in various records and documents across different regions of England. These early spellings suggest a connection to the Old English words "ac" meaning oak and "hyrne" meaning a corner or an angle, potentially referring to a location near an oak tree or a valley.
In the 14th century, a notable figure bearing the ACHORN surname was John Achorn, who was born in Somerset, England, around 1320. He was a prominent landowner and served as a member of the local gentry. Records from this period also indicate that the name was prevalent in the counties of Somerset, Devon, and Dorset.
As time passed, the spelling of the name evolved further, with variations such as "Achorne" and "Ackhorn" appearing in various historical documents and records. In the 16th century, a notable individual named William Achorn was born in 1542 in Devon, England, and served as a respected member of the local community.
During the 17th century, the ACHORN surname gained prominence in the New World as some members of the family emigrated to the American colonies. One of the earliest recorded individuals was Nicholas Achorn, who was born in 1645 in Marblehead, Massachusetts, and became a prominent figure in the community.
Another notable individual was Captain Samuel Achorn, who was born in 1712 in Boston, Massachusetts. He served as a captain in the British Royal Navy and played a significant role in various naval engagements during the 18th century.
Throughout the 19th century, the ACHORN surname continued to be documented in various regions of the United States, with individuals bearing this name making notable contributions in various fields, such as politics, business, and academia.
Demographics
Among Census respondents with the surname Achorn, the largest self-reported group is White at 92.4%. The next largest groups are Two or More Races (4.8%) and Hispanic (1.4%).
The bar chart below shows how Achorn 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 Achorn surname at the time of the 2020 Census, not any inherent property of the name itself.
