Origin
Meaning and origin of Mawhorr
The surname MAWHORR is believed to have originated in England during the early Middle Ages. It is thought to be derived from the Old English words "māw" meaning "gull" and "horr" meaning "gray" or "old". This suggests that the name may have initially referred to someone with gray hair or an older person.
One of the earliest known records of the MAWHORR name dates back to the Domesday Book of 1086, where it appears as "Mauric de Mauhorr". This entry is believed to refer to a landowner or tenant in the county of Shropshire. Other early spellings include "Mawhor", "Mawhore", and "Maughorre".
In the 13th century, a man named John MAWHORR was recorded as a resident of the village of Mawhorr in Staffordshire. This place name likely derived from the surname itself, indicating that it was already well-established in the area by that time.
During the 14th century, a notable figure bearing the MAWHORR surname was Sir William MAWHORR (c. 1310 - 1378), a knight and landowner in Warwickshire. He was involved in various military campaigns during the Hundred Years' War and served as a member of the King's Council.
Another prominent individual was Thomas MAWHORR (c. 1425 - 1498), a wealthy merchant and alderman in the city of London. He was known for his philanthropic efforts and contributed to the construction of several churches and almshouses in the capital.
In the 16th century, the MAWHORR name appeared in the records of the College of Arms, with the granting of a coat of arms to the family of Richard MAWHORR (c. 1520 - 1586), a landowner in Gloucestershire.
During the English Civil War in the 17th century, a Royalist soldier named John MAWHORR (c. 1605 - 1670) fought for King Charles I and was later rewarded with lands in Oxfordshire for his loyalty.
The MAWHORR surname continued to be found throughout various parts of England in subsequent centuries, with individuals bearing the name working in various professions and industries.

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 Mawhorr surname at the time of the 2020 Census, not any inherent property of the name itself.

Does the Census include every surname?

There are two main reasons: rounding and suppression. The Census Bureau rounds published values, and it may suppress very small cells to protect privacy.
