Origin
Meaning and origin of Mordick
The surname Mordick has its origins in the historic county of Westphalia, Germany, tracing back to the 13th century. It is believed to have derived from the Middle Low German word "mordik," meaning "murderous" or "warlike." This suggests the name may have been initially bestowed upon someone with a fierce or aggressive demeanor.
One of the earliest recorded instances of the name appears in the Wibaldian Codex, a 13th-century manuscript from the Cistercian abbey of Altenberg, near Cologne. It mentions a "Henricus Mordick" who was a landowner in the village of Essen-Werden.
By the 15th century, the name had spread to various regions of Germany, including Brandenburg and Saxony. In the town of Gransee, northeast of Berlin, a "Claus Mordick" is documented as a merchant and landholder in 1473.
The earliest known bearer of the name in England was Hans Mordick, a German merchant who settled in London in the late 16th century. He is recorded in the parish registers of St. Olave's Church in 1589.
Notable individuals with the surname Mordick include Johann Mordick (1640-1712), a German Lutheran pastor and theologian who served in the town of Halberstadt. Another was Friedrich Mordick (1753-1809), a Prussian military officer who fought in the Napoleonic Wars.
In the 19th century, the name gained prominence with the birth of Wilhelm Mordick (1835-1912), a German-American banker and philanthropist who emigrated to New York City in 1857. He co-founded the Mordick & Co. banking house and was a significant benefactor to educational institutions.
Another notable figure was Karl Mordick (1868-1942), a German-born American artist renowned for his landscape paintings. He was a member of the Boston Art Club and exhibited his works at the prestigious National Academy of Design.
The surname Mordick can also be found in historical records from the Netherlands, where it is believed to have originated from the same linguistic roots as the German variant. One notable bearer was Pieter Mordick (1792-1868), a Dutch merchant and shipowner based in Amsterdam.

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