Origin
Meaning and origin of Karickhoff
The surname Karickhoff originates from Germany, with its earliest known records dating back to the 16th century. It is believed to be derived from the Old German word "karich," which means "marsh" or "bog," and "hoff," meaning a fenced-in area or a small settlement. This suggests that the name may have originated from a place where the earliest bearers of the name resided, potentially near a marshy area enclosed by fences or fortifications.
One of the earliest recorded instances of the name Karickhoff can be found in the church records of the town of Wittenberg, in the German state of Saxony-Anhalt, where a certain Hans Karickhoff was mentioned in a baptismal record dated 1572. Another notable early reference is found in the tax records of the city of Leipzig in 1598, where a Johann Karickhoff is listed as a landowner.
The name Karickhoff has also been associated with several notable individuals throughout history. One such figure is Heinrich Karickhoff, a German mathematician and astronomer who lived in the early 17th century (1585-1647). He is known for his contributions to the study of celestial mechanics and his work on improving astronomical tables and calculations.
Another individual of note is Bernhard Karickhoff (1639-1712), a German theologian and pastor who served in the city of Hamburg during the late 17th and early 18th centuries. He is remembered for his influential sermons and writings on Christian doctrine and ethics.
In the 19th century, the name Karickhoff gained prominence with the birth of Otto Karickhoff (1823-1898), a German industrialist and entrepreneur who founded one of the earliest steel manufacturing companies in the Ruhr region of Germany. His company played a significant role in the industrialization of the area and contributed to the economic development of the region.
Another notable figure is Frieda Karickhoff (1879-1957), a German artist and painter known for her landscape and portrait works. She studied at the renowned Académie Julian in Paris and gained recognition for her impressionistic style and her ability to capture the essence of her subjects.

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.
