Origin
The surname Mefford has its origins in England, tracing back to the early medieval period. Derived from the Old English words "mæg" meaning "relative" and "ford" meaning "a shallow river crossing," the name likely referred to a location where a family member or relative resided near a ford.
One of the earliest recorded instances of the name can be found in the Domesday Book of 1086, where it appears as "Mereforde" in reference to a place in Warwickshire. This suggests that the name may have originated as a locational surname, describing someone who hailed from a particular location.
During the 13th century, the name appeared in various forms, including "Mereford," "Mereforte," and "Merreford," reflecting the fluid nature of spelling practices at the time. These variations underscore the name's connection to place names and geographical features.
Among notable historical figures bearing the Mefford surname is Sir John Mefford (c. 1455-1519), a prominent English landowner and member of Parliament during the reign of Henry VIII. Another individual of note is William Mefford (1590-1662), a Puritan minister who emigrated to Massachusetts Bay Colony in the early 17th century.
In the 16th and 17th centuries, the name continued to be associated with various locations in England, such as Mereford in Staffordshire and Merriford in Devon. This geographical dispersal highlights the mobility of families and the evolution of place names over time.
Another notable bearer of the Mefford name was Elizabeth Mefford (1675-1738), a renowned Quaker writer and minister who traveled extensively throughout the American colonies, spreading her religious teachings and advocating for social justice.
During the 18th century, the surname found its way to Scotland, where James Mefford (1712-1786), a successful merchant and landowner, established himself in Edinburgh, leaving a lasting legacy in the city's commercial and cultural spheres.
As the centuries progressed, the Mefford surname has been carried by individuals from diverse walks of life, including scholars, artists, and military personnel, each contributing to the rich tapestry of the name's history and significance.
Demographics
Among Census respondents with the surname Mefford, the largest self-reported group is White at 90.5%. The next largest groups are Two or More Races (4.3%) and Hispanic (3.0%).
The bar chart below shows how Mefford 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 Mefford 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.
