Origin
Meaning and origin of Deroest
The surname DEROEST originated in the Netherlands, emerging in the late 16th century. It is derived from the Dutch words "de" and "roest," meaning "the rust." This suggests the name may have originated as a descriptive nickname for someone who worked with iron or lived near a rusty object.
Early records indicate the DEROEST name was concentrated in the provinces of North Holland and South Holland, particularly around the cities of Amsterdam and Rotterdam. Variations in spelling include DeRoest, De Roest, and De Roost.
One of the earliest known references to the DEROEST surname is found in the Amsterdam Civic Guard archives from the 1600s. These records document a Pieter DEROEST who served in the city's militia in 1632.
The DEROEST name also appears in several historic Dutch church records from the 17th and 18th centuries. For instance, a Jacob DEROEST is listed in the baptismal records of the Oude Kerk in Amsterdam, with his son Hendrik being baptized in 1701.
Notable individuals throughout history who bore the DEROEST surname include Herman DEROEST (1667-1741), a Dutch Golden Age painter known for his still-life works. Another prominent figure was Nicolaas DEROEST (1786-1867), a Dutch politician and jurist who served as the Attorney General of the Netherlands from 1838 to 1851.
In the 19th century, several DEROEST family members emigrated from the Netherlands to the United States and Canada, bringing the name to North America. One such immigrant was Johannes DEROEST (1821-1902), who settled in Iowa and became a prominent farmer and landowner.
Other notable DEROEST individuals include Cornelius DEROEST (1872-1945), a Dutch-American architect based in New York City who designed several churches and public buildings, and Johanna DEROEST (1890-1976), a Dutch writer and poet who published several collections of poetry in the early 20th century.

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