Origin
The surname TROCHE has its origins in France, where it first emerged in the early 14th century. It derived from the Old French word "troche", meaning a bundle or bundle of sticks, suggesting that the name may have initially referred to someone who worked with bundles or bundles of wood.
One of the earliest recorded instances of the TROCHE surname can be found in the historic French town of Troyes, located in the Aube department of northeastern France. In a manuscript dated 1327, a certain Guillaume Troche is mentioned as a resident of the town, potentially indicating that the name originated in this region.
During the 15th century, the TROCHE name began to appear more frequently in various records and documents across France. For instance, in 1468, a Pierre Troche is listed as a merchant in the city of Lyon, while in 1492, a Jacques Troche is recorded as a landowner in the village of Sancerre.
As the centuries passed, the TROCHE surname spread to other parts of Europe. In the 16th century, a notable figure bearing this name was the French humanist scholar and poet, Guillaume Michel de la Troche (1505-1585), who was born in Poitiers and is remembered for his translations of ancient Greek and Latin works.
In the 17th century, the TROCHE name found its way to England, where it was anglicized to the spelling "Troch". One of the earliest recorded instances of this variation was in 1642, when a John Troch is mentioned in parish records from the village of Bromley in Kent.
Another notable individual with the TROCHE surname was the 18th-century French architect and engineer, Jean-Charles Troche (1742-1810), who was responsible for the design and construction of several important buildings and bridges in Paris and its surrounding regions.
As the centuries progressed, the TROCHE name continued to spread across Europe and beyond, with various families bearing this surname making their mark in different fields and professions. Some other notable figures throughout history include the 19th-century French painter, Louis Troche (1825-1901), and the 20th-century Argentine author and journalist, Mariano Troche Arce (1920-2001).
Demographics
Among Census respondents with the surname Troche, the largest self-reported group is Hispanic at 87.2%. The next largest groups are White (9.4%) and Black (2.2%).
The bar chart below shows how Troche 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 Troche surname at the time of the 2020 Census, not any inherent property of the name itself.

No. The Census Bureau only publishes surnames that appeared at least 100 times in a given decennial Census. That means very rare surnames are excluded entirely, and a surname can appear in one Census release but disappear from a later one if it falls below the reporting threshold.
There are two main reasons: rounding and suppression. The Census Bureau rounds published values, and it may suppress very small cells to protect privacy. For 2020, the Bureau also published raw group counts rather than direct percentages, so Name Census converts those counts back into shares for comparability across census years.
