The history of the last name Cayou

The surname Cayou is believed to have originated in France, specifically in the region of Normandy, during the medieval period. It is derived from the Old French word "caillou," which means "pebble" or "small stone." This suggests that the name may have initially been given as a descriptive nickname to someone who lived near a stony area or worked with stones.

One of the earliest recorded instances of the name Cayou can be found in the Rolls of Normandy, a collection of medieval records from the 11th and 12th centuries. In these rolls, the name appears as "de Caillou," indicating that it was likely a locative surname, referring to a person's place of origin or residence.

The Cayou name can also be traced back to the time of the Norman Conquest of England in 1066. During this period, many Norman families, including those bearing the Cayou surname, settled in various parts of England, particularly in the counties of Hampshire and Sussex.

In the 13th century, a prominent figure named Roger de Caillou was mentioned in the Pipe Rolls of Gloucestershire, which were administrative records documenting tax payments and financial transactions. This entry provides evidence of the surname's presence in England during that time.

Another notable bearer of the Cayou name was Jean Caillou, a French poet and writer who lived in the 16th century (c. 1530 - 1590). His works, which included poetry and literary criticism, were widely recognized and contributed to the cultural landscape of Renaissance France.

During the 17th century, the Cayou surname appeared in various parish records and legal documents across France and England. For instance, in 1642, a man named Pierre Cayou was recorded in the parish registers of Saint-Germain-des-Prés in Paris.

In the 18th century, a prominent figure bearing the Cayou surname was Jean-Baptiste Cayou (1725 - 1795), a French architect and urban planner. He was responsible for designing several notable buildings and public spaces in Paris, including the Place des Victoires and the Palais de la Bourse.

Another individual with the Cayou surname who gained recognition was Marie-Antoinette Cayou (1777 - 1845), a French painter and portraitist. She was known for her skillful depictions of aristocratic figures and her works were exhibited at the Paris Salon during the early 19th century.
