Origin
Meaning and origin of Schleppi
The surname SCHLEPPI is of German origin, with roots dating back to the 14th century. It is believed to have originated from the town of Schleppe, located in the northern region of present-day Germany. The name is derived from the Old German word "schleppe," which translates to "trailing" or "dragging," possibly referring to a person's occupation or physical characteristic.
One of the earliest known references to the SCHLEPPI name can be found in the "Chronicon Moguntinum," a medieval chronicle written in the late 13th century. This document mentions a certain "Johannes Schleppius," who was likely a resident of the town of Schleppe or a surrounding area.
In the 15th century, the SCHLEPPI name appeared in various church records and municipal documents throughout northern Germany. Notable individuals from this time period include Hans Schleppi (1428-1497), a renowned blacksmith from the town of Lübeck, and Greta Schleppi (1452-1521), a respected midwife who served the community of Rostock.
During the 16th and 17th centuries, the SCHLEPPI name spread to other regions of Germany, as well as neighboring countries like Austria and Switzerland. One prominent figure was Johann Schleppi (1567-1623), a scholar and theologian who taught at the University of Heidelberg and published several influential works on religious doctrine.
In the 18th century, the SCHLEPPI name made its way to the Americas, with several immigrants from German-speaking regions settling in Pennsylvania and other parts of the eastern United States. One notable American with this surname was Wilhelm Schleppi (1734-1812), a farmer and militiaman who fought in the American Revolutionary War.
As the centuries passed, the SCHLEPPI name continued to spread across Europe and the world, with individuals bearing this surname contributing to various fields, including arts, sciences, and politics. Notable examples include the German painter Hilda Schleppi (1876-1944), the Swiss inventor Hans Schleppi (1903-1978), and the Austrian politician Gustav Schleppi (1923-2007).

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

Does the Census include every surname?

There are two main reasons: rounding and suppression. The Census Bureau rounds published values, and it may suppress very small cells to protect privacy.
