Origin
Meaning and origin of Tochtrop
The surname TOCHTROP has its origins in the Netherlands, dating back to the 16th century. It is believed to have derived from the Dutch phrase "tocht op," which means "journey upon." This suggests that the name may have been given to someone who traveled frequently or was a merchant or trader.
One of the earliest recorded instances of the TOCHTROP name can be found in the Dutch town of Breda in 1587. A merchant named Jan TOCHTROP is mentioned in a local registry, indicating that the name was already well-established in the region at that time.
In the 17th century, the TOCHTROP name appeared in various records across the Netherlands, particularly in the provinces of Noord-Brabant and Zeeland. Some notable individuals from this period include Pieter TOCHTROP (1612-1683), a prominent merchant and landowner in the city of Rotterdam, and Adriaan TOCHTROP (1643-1718), a respected lawyer and judge in the city of Middelburg.
As the Dutch expanded their global trade and colonial ventures, the TOCHTROP name began to appear in other parts of the world. In the late 17th century, a merchant named Cornelis TOCHTROP (1668-1732) settled in the Dutch colony of Batavia (present-day Jakarta, Indonesia), where he established a successful trading company.
During the 18th century, the TOCHTROP family continued to play a role in Dutch society. One notable figure was Willem TOCHTROP (1721-1798), a renowned painter and engraver from Amsterdam, whose works are still highly valued by art collectors today.
In the 19th century, the TOCHTROP name spread further across Europe and beyond. A notable figure from this period was Frederick TOCHTROP (1824-1891), a German-born explorer and naturalist who traveled extensively in South America and made significant contributions to the study of Amazonian flora and fauna.
Throughout its history, the TOCHTROP name has been associated with various professions, including merchants, lawyers, artists, and explorers. While the name may have originated from humble beginnings, it has left its mark on various aspects of Dutch and European history over the centuries.

The bar chart below shows how Tochtrop 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 Tochtrop surname at the time of the 2020 Census, not any inherent property of the name itself.
