Origin
Meaning and origin of Cadichon
The surname Cadichon is of French origin, with its roots traced back to the 14th century in the region of Normandy, France. It is believed to have derived from the Old French word "cadelan," which referred to a small, thin cake or pastry. This suggests that the name may have originally been an occupational surname for a baker or pastry maker.
One of the earliest recorded instances of the name Cadichon can be found in the Rollon Rolls of Normandy, dated around 1180, where a certain Radulfus Cadichon is listed. This document contains the names of those who accompanied Rollo, the first Duke of Normandy, during his conquest of the region.
In the 13th century, the name appears in various medieval records and manuscripts, such as the Testa de Nevill, a census-like document compiled in 1219 during the reign of King Henry III. This document lists a Willelmus Cadichon as a landowner in the county of Lincolnshire, England.
The Domesday Book, a comprehensive survey of landowners and property commissioned by William the Conqueror in 1086, does not appear to contain any direct references to the surname Cadichon. However, it is possible that the name may have been recorded under alternative spellings or variations.
One notable figure bearing the Cadichon name was Jean Cadichon, a French clergyman who lived in the 15th century (c. 1400-1473). He served as the Bishop of Avranches from 1457 until his death and was known for his efforts in strengthening the religious and educational institutions in his diocese.
Another individual of note was Guillaume Cadichon (c. 1510-1580), a French merchant and explorer who is credited with being one of the first Europeans to establish trade relations with Japan in the mid-16th century. His explorations and voyages contributed to the expansion of French commercial interests in Asia.
In the realm of literature, the French poet and playwright Charles Cadichon (1635-1712) gained recognition for his works during the 17th century. He was a member of the Académie Française and known for his tragedies and comedies performed in Paris.
The name Cadichon can also be traced to various locations and place names throughout France, such as the village of Cadichon in the department of Yonne, and the commune of Cadichon-sur-Gardon in the department of Gard.
Additionally, the surname Cadichon has been associated with the noble family of Cadichon de Champréaux, who held estates and lands in the region of Poitou during the 16th and 17th centuries. Notable members of this family include François Cadichon de Champréaux (c. 1550-1625), a French military commander and governor of the city of La Rochelle.

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