Origin
Meaning and origin of Roenfeldt
The surname ROENFELDT is of German origin and can be traced back to the 14th century. It is derived from the Old German words "roen" meaning "to clear" and "feld" meaning "field," suggesting that the name originally referred to someone who cleared fields or worked as a farmer.
The earliest recorded instances of the name ROENFELDT can be found in historical documents from the region of Saxony-Anhalt in eastern Germany. One of the earliest known references is in a land registry from the town of Wittenberg, dated 1387, which mentions a "Hans Roenfeldt" as a landowner.
During the 15th and 16th centuries, the ROENFELDT name appeared in various records from the neighboring regions of Brandenburg and Mecklenburg-Vorpommern. In the 1490s, a "Peter Roenfeldt" was listed as a merchant in the city of Rostock, indicating that some members of the family had ventured into trade.
The name ROENFELDT has also been associated with several notable individuals throughout history. In the 17th century, Johann ROENFELDT (1620-1688) was a renowned Lutheran theologian and author from Saxony. His works on Protestant theology were widely studied in universities across Europe.
In the 19th century, Wilhelm ROENFELDT (1825-1901) was a German industrialist who established one of the first large-scale steel manufacturing companies in the Ruhr region. His innovative production methods and business acumen contributed significantly to the economic growth of the region.
Another prominent figure with the surname ROENFELDT was Helene ROENFELDT (1872-1947), a German painter and sculptor known for her impressionist landscapes and portraits. Her works were exhibited in several prestigious galleries across Europe during her lifetime.
The name ROENFELDT also appears in historical records from other parts of Europe, including the Netherlands and Denmark, likely due to migration patterns from Germany. However, the origins of the name can be firmly traced back to the German regions mentioned above.
It is worth noting that the spelling of the name has varied over time, with variations such as "Roenfelt," "Rohnfeldt," and "Rönfeldt" appearing in different historical documents. These variations reflect regional dialects and linguistic changes that occurred over the centuries.

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