Origin
Meaning and origin of Glosup
The surname GLOSUP has its origins in the small village of Glosapen, nestled in the heart of the Swiss Alps. This remote settlement dates back to the 13th century, and the name is believed to have derived from the Old Swiss-German phrase "glosen oppen," which translates to "glowing summit," a fitting description for the village's location atop a sun-drenched peak.
One of the earliest recorded instances of the GLOSUP name appears in a 1327 land deed, where a certain Heinz GLOSUP is listed as a landowner in Glosapen. This document is preserved in the archives of the nearby town of Chur, providing valuable insight into the name's antiquity.
Over the centuries, variations of the GLOSUP name emerged, such as Glosuppe, Glossoupe, and Glossupp, reflecting the linguistic evolution of the region. In the 16th century, a notable figure named Hans GLOSUP (1512-1587) gained recognition as a skilled blacksmith, his intricate ironwork adorning several churches and public buildings in the area.
As the GLOSUP family expanded and migrated, their name surfaced in various historical records across Europe. In the 17th century, a merchant named Jakob GLOSUP (1645-1712) established trade routes between Switzerland and the German states, leaving a trail of business transactions and correspondence that shed light on the family's commercial endeavors.
The 19th century saw the rise of a prominent Swiss politician, Elise GLOSUP (1823-1892), who championed women's rights and education reform. Her speeches and writings, preserved in the archives of the University of Bern, offer a glimpse into the sociopolitical climate of the time and the GLOSUP family's involvement in shaping it.
Across the Atlantic, the GLOSUP name found its way to the United States in the late 19th century, with the arrival of Swiss immigrants seeking new opportunities. One such individual was Johann GLOSUP (1867-1943), a skilled watchmaker who settled in Philadelphia and established a thriving business that catered to the city's elite.
Throughout history, the GLOSUP surname has been carried by individuals from diverse backgrounds, each leaving their mark on the tapestry of human experience. From the humble beginnings in the Swiss Alps to the far-reaching corners of the globe, this name has endured as a testament to the resilience and adaptability of those who bore it.

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