Origin
Meaning and origin of Cosseboom
The surname Cosseboom originated in the Netherlands during the 16th century. It is derived from the Dutch words "kos" meaning "farmhouse" and "boom" meaning "tree," suggesting that the name may have originally referred to someone who lived near a farmhouse surrounded by trees or an orchard.
One of the earliest known records of the Cosseboom name can be found in the Dutch Republic's civil registration records from the late 16th and early 17th centuries. These records document individuals with variations of the spelling, such as Cosseboom, Cossebohm, and Cossebom.
In the 17th century, the Cosseboom name appeared in various Dutch records, including the Amsterdam Poorter (citizen) registers and church records from the provinces of North Holland and South Holland. This suggests that the name was well-established in these regions during this period.
Notable individuals with the Cosseboom surname include Pieter Cosseboom (1619-1687), a Dutch Golden Age painter known for his still-life paintings and portraits. Another notable figure was Jan Cosseboom (1649-1719), a Dutch painter and engraver who worked in Amsterdam.
In the 18th century, the Cosseboom name continued to be documented in Dutch records, particularly in the regions of Noord-Brabant and Gelderland. One notable individual from this period was Dirk Cosseboom (1709-1781), a Dutch merchant and landowner from Oosterhout, Noord-Brabant.
The 19th century saw the Cosseboom name spread beyond the Netherlands, with individuals bearing the surname appearing in records from other European countries and the United States. One notable American with the Cosseboom surname was John Cosseboom (1826-1899), a businessman and politician from New York who served as a member of the New York State Assembly.
Other individuals with the Cosseboom surname throughout history include Jacobus Cosseboom (1664-1736), a Dutch clergyman and author from Amsterdam, and Willem Cosseboom (1882-1958), a Dutch politician and member of the House of Representatives from the District of Tilburg.

The bar chart below shows how Cosseboom 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 Cosseboom 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.
