Origin
Meaning and origin of Vonmoos
The surname VONMOOS has its origins in Switzerland, tracing back to the 15th century. The name is derived from the German word "Moos," meaning "moss" or "peat bog," indicating that the earliest bearers of this name likely resided in or near a marshy area.
The first recorded instances of the VONMOOS name can be found in historical documents from the canton of Bern, Switzerland. In 1487, a man named Hans von Moos is mentioned in the municipal records of the city of Bern, suggesting the name's longstanding presence in the region.
One of the earliest known bearers of the VONMOOS name was Jakob von Moos (1486-1549), a Swiss Protestant reformer and theologian. He played a significant role in the Reformation movement in Switzerland and was a close associate of Huldrych Zwingli.
Another notable figure was Johann Rudolf von Moos (1658-1719), a Swiss military officer and diplomat. He served as the ambassador of the Swiss Confederacy to France and played a crucial role in negotiating the Peace of Utrecht in 1713, which ended the War of the Spanish Succession.
In the 19th century, the VONMOOS name gained prominence with the birth of Johann Baptist von Moos (1828-1895), a Swiss politician and jurist. He served as the President of the Swiss Federal Court and was a member of the Federal Council, the executive branch of the Swiss government.
The surname also has a connection to the world of arts and literature. Karl Friedrich von Moos (1810-1876) was a Swiss painter and etcher known for his landscape paintings and etchings depicting the Swiss Alps.
Over the centuries, the VONMOOS name has maintained its presence in Switzerland and has been carried by numerous individuals, including Johann von Moos (1774-1846), a Swiss politician and member of the Helvetic Republic's government, and Hans von Moos (1908-1993), a Swiss architect known for his modernist designs.
While the VONMOOS surname originated in Switzerland, it has since spread to other parts of the world due to migration and family connections. However, its roots can be traced back to the Swiss regions, where it has a rich historical significance and a long-standing presence.

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.
