The history of the last name Koos

The surname KOOS has its origins in the Netherlands, with records dating back to the late 16th century. It is believed to be a Dutch variant of the German surname KUHLS or KUEHLS, which derives from the Middle Low German word "kūl" meaning "small hill" or "mound." This suggests that the name may have initially referred to someone who lived near a small hill or mound.

One of the earliest recorded instances of the KOOS surname can be found in the Dutch city of Dordrecht in 1593, where a certain Adriaen Jansz KOOS was listed in municipal records. The name also appears in various church records and legal documents from the 17th and 18th centuries across the Netherlands, with variations in spelling such as KOES and KOOSE.

Historically, KOOS was a predominantly coastal surname, with concentrations in the provinces of Zuid-Holland, Zeeland, and Noord-Holland. This geographic distribution suggests that the name may have originated among those who lived near the dunes or small hills along the Dutch coastline.

A notable individual bearing the KOOS surname was Pieter Jansz KOOS (1597-1672), a Dutch Golden Age painter known for his genre scenes depicting tavern life and peasant revelry. His works are held in collections at the Rijksmuseum in Amsterdam and the Mauritshuis in The Hague.

Another historical figure was Adriaen Pietersz KOOS (1621-1691), a Dutch naval officer who served in the Anglo-Dutch Wars and rose to the rank of Vice Admiral in the Dutch Navy. He played a significant role in several naval battles against the English and French fleets during the latter half of the 17th century.

In the 18th century, Cornelis KOOS (1737-1803) was a prominent Dutch merchant and shipowner based in Rotterdam. His business dealings extended across Europe and the Americas, and he was known for his involvement in the lucrative trade of spices and textiles.

The surname KOOS also has a connection to the Netherlands Antilles, with records indicating that a branch of the family emigrated to the Dutch Caribbean island of Curaçao in the late 18th century. One notable descendant was Hendrik KOOS (1801-1872), a plantation owner and influential figure in the colonial administration of Curaçao.

In the 19th century, Jan KOOS (1818-1892) was a Dutch architect who designed several notable buildings in The Hague, including the Nieuwe Kerk and the Binnenhof complex, which houses the Dutch parliament. His work was instrumental in shaping the architectural landscape of the city during that period.
