Origin
Meaning and origin of Sustache
The surname "SUSTACHE" is believed to have originated in France during the medieval period. It is thought to be derived from the Old French words "sus" meaning "above" and "tache" meaning "spot" or "mark". This suggests that the name may have originally referred to a person who lived near a landmark or geographical feature that was marked or distinguished in some way.
The earliest known recorded instances of the name "SUSTACHE" can be found in various historical documents from the 13th and 14th centuries in the regions of Normandy and Brittany in northern France. These include mentions in parish records, land deeds, and legal documents of the time.
One notable historical figure who bore the surname "SUSTACHE" was Jean Sustache, a French explorer and navigator who was born in Normandy in 1521. He is known for his voyages to the West Indies and the Caribbean in the late 16th century, during which he mapped and documented many previously uncharted islands and coastlines.
Another individual of note was Marie Sustache, a French noblewoman who lived in the 17th century. She was a prominent figure in the court of King Louis XIV and is recorded as having played a significant role in the diplomatic negotiations between France and Spain during the War of the Spanish Succession.
In the 18th century, there was a renowned French artist named Pierre Sustache, who was born in 1725 and died in 1798. He was a painter and engraver known for his detailed landscapes and portraits, many of which can still be found in various art galleries and museums across France and Europe.
Moving into the 19th century, one notable bearer of the "SUSTACHE" surname was Antoine Sustache, a French soldier and military leader who fought in the Napoleonic Wars. He rose through the ranks to become a general in Napoleon's army and participated in several major battles, including the Battle of Waterloo in 1815.
Lastly, in the early 20th century, there was a French novelist and playwright named Émile Sustache, who was born in 1876 and died in 1942. He was known for his works exploring themes of love, loss, and the human condition, and his plays were performed in theaters across France during his lifetime.
While the surname "SUSTACHE" is not among the most common in France, it has a rich and interesting history that spans several centuries and includes notable figures from various fields and professions.

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