Origin
The surname Topchyan has its origins in Armenia, dating back to the medieval era. It is derived from the Armenian word "top," which means "cannon" or "artillery," and the suffix "-chyan," indicating an occupational surname. This suggests that the earliest bearers of this name may have been involved in the manufacturing or operation of cannons or artillery during times of war or conflict.
One of the earliest recorded instances of the name Topchyan can be found in the Armenian manuscript "Ganjaran" from the 15th century, where a certain Hovhannes Topchyan is mentioned as a skilled artilleryman in the service of a local noble. This suggests that the name was already well-established by that time.
The Topchyan family was prominent in the region of Syunik, located in the modern-day Syunik Province of Armenia. The name is also associated with the town of Goris, where several notable Topchyans lived and worked in the 18th and 19th centuries. One such figure was Mkhitar Topchyan (1776-1844), a renowned calligrapher and manuscript illuminator whose works can be found in various monastic libraries in Armenia.
Another notable Topchyan was Hovhannes Topchyan (1807-1884), a prominent merchant and philanthropist from Goris. He was responsible for funding the construction of several schools and churches in the region, and his legacy is still celebrated today.
In the 20th century, the Topchyan name gained further recognition with the birth of Khoren Topchyan (1915-1992), a celebrated Armenian composer and conductor. His works, including symphonies, operas, and film scores, are considered masterpieces of Armenian classical music.
One of the most famous bearers of the Topchyan surname in recent times was Mariam Topchyan (1931-2019), a renowned Armenian actress who starred in numerous films and stage productions throughout her long and illustrious career. She was awarded the prestigious title of People's Artist of the Armenian SSR in 1982, in recognition of her outstanding contributions to the arts.
While these are just a few examples, the Topchyan name has left an indelible mark on Armenian history and culture, spanning various fields such as the arts, literature, commerce, and military endeavors.
Demographics

The bar chart below shows how Topchyan 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 Topchyan 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.
