Origin
Meaning and origin of Billiot
The surname Billiot is of French origin, tracing its roots back to the region of Normandy in northern France during the Middle Ages. It is believed to have derived from the Old French word "billette," meaning a small log or billet of wood. This suggests that the name may have initially been an occupational surname for someone who worked with wood, such as a woodcutter or a carpenter.
The earliest known record of the Billiot name dates back to the 13th century, where it appeared in various medieval documents and records from the Normandy region. One notable mention is found in the Livre des Bourgeois de Rouen, a register of the citizens of Rouen, which lists a certain Jehan Billiot in the year 1292.
During the 14th century, the name Billiot began to spread beyond Normandy as people migrated to other parts of France and Europe. In 1356, a man named Guillemin Billiot was recorded as a resident of the town of Montdidier, located in the historical province of Picardy.
The Billiot surname also made its way across the English Channel, where it appeared in some early English records. In the Lay Subsidy Rolls of 1334, which were tax records compiled during the reign of King Edward III, there is an entry for a Thomas Byllyot residing in the county of Somerset.
As the centuries passed, the Billiot name continued to be documented in various historical records and manuscripts across Europe. One notable figure bearing this surname was Jean-Baptiste Billiot, a French painter and engraver who lived from 1639 to 1715. He was recognized for his intricate etchings and engravings of religious subjects.
Another prominent individual with the Billiot surname was François-Joseph Billiot, a French military officer who served during the French Revolutionary Wars and the Napoleonic Wars. Born in 1771, he rose through the ranks and became a brigadier general, distinguishing himself in several battles before his death in 1818.
In the 19th century, a man named Théodore Billiot gained recognition as a French sculptor and medallist. He was born in 1825 and is known for his intricate sculpted works, including medals and medallions commemorating important historical events and figures.
Moving into the 20th century, one notable bearer of the Billiot surname was Émile Billiot, a French painter and illustrator who lived from 1876 to 1961. He was renowned for his vibrant landscapes and scenes depicting rural life in France.
Throughout its long history, the Billiot surname has also been associated with various place names and locations, particularly in France. For example, the village of Billiot in the department of Manche, Normandy, likely derived its name from an early settler or landowner with the Billiot surname.

Does the Census include every surname?
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.
Why don't the ancestry percentages always add up to exactly 100%?
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.
