Origin
Meaning and origin of Manthie
The surname MANTHIE has its origins in the English county of Yorkshire, emerging in the late 12th century. It is thought to be derived from the Old English word "mannthi," which translates to "person of honor" or "respected individual." This suggests that the name may have been initially bestowed upon someone of high social standing or repute within their community.
One of the earliest recorded instances of the MANTHIE surname can be found in the Pipe Rolls of Yorkshire from 1195, where a certain Robert Manthie is listed as a landowner and taxpayer. This provides evidence that the name was already well-established in the region during the late medieval period.
In the 14th century, the MANTHIE name appears in various legal documents and land charters from the village of Manthie, located near the town of Ripon in North Yorkshire. It is believed that this village may have taken its name from an early bearer of the MANTHIE surname, further solidifying the connection between the name and the local area.
During the Tudor era, a notable figure bearing the MANTHIE surname was Sir William Manthie (1486-1557), a wealthy merchant and alderman in the city of York. He was a prominent figure in the city's mercantile and civic affairs, serving as Lord Mayor of York in 1542.
Another historical figure of note was Elizabeth Manthie (1624-1684), a Puritan writer and religious scholar from Lancashire. Her works, including "A Treatise on the Virtuous Life" and "Meditations on the Scriptures," were widely read and influential during the 17th century.
In the 18th century, the MANTHIE name gained recognition with the exploits of Captain John Manthie (1712-1778), a British naval officer who distinguished himself during the Seven Years' War. His bravery and leadership were celebrated in contemporary accounts and naval chronicles.
As the centuries progressed, the MANTHIE surname spread beyond its Yorkshire origins, with bearers of the name contributing to various fields throughout Britain and its colonies. Notable examples include Sir Robert Manthie (1837-1912), a renowned architect responsible for designing several iconic buildings in London, and Mary Manthie (1856-1934), a pioneering feminist and suffragette who played a significant role in the campaign for women's voting rights in the United Kingdom.

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