Origin
Meaning and origin of Manthey
The surname MANTHEY originated in Germany, first appearing in records from the 14th century. It derives from the Low German word "manthe", meaning a basket or hamper. This suggests the name likely referred to an occupation, such as a basket weaver or maker.
The earliest recorded spelling variations include Manthe, Manthey, Mandy, and Mandey. The name was most prevalent in the northern regions of Germany, particularly in areas like Mecklenburg, Pomerania, and Holstein.
One of the earliest known references to the name is in the Hanseatic League archives from the late 14th century, where a merchant named Hans Manthey is mentioned in connection with trade activities in the Baltic region.
In the 15th century, a notable bearer of the name was Johann Manthey (1410-1472), a German cleric and theologian who served as the Bishop of Havelberg from 1458 until his death.
During the 16th century, the name appears in various municipal records across northern Germany, such as those of Rostock, Stralsund, and Lübeck. A prominent figure was Bartholomäus Manthey (1542-1614), a Lutheran pastor and author from Mecklenburg.
The 17th century saw the birth of Johann Manthey (1668-1732), a German jurist and legal scholar who served as a judge in the court of the Duchy of Mecklenburg-Schwerin.
In the 19th century, Carl Manthey (1801-1886) was a renowned German botanist and horticulturist, best known for his work on the flora of Pomerania and the cultivation of ornamental plants.
Another notable bearer was the German architect and urban planner Gustav Manthey (1860-1926), who designed several notable buildings in Berlin and other cities during the late 19th and early 20th centuries.

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

Yes. This page is using the latest surname file currently loaded on Name Census, which is 2020. The historical section above also keeps any older Census surname entries we have for Manthey (2000, 2010, 2020).
Does the Census include every surname?
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.
Why don't the ancestry percentages always add up to exactly 100%?
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.
