The history of the last name Rois

The surname ROIS is of French origin, derived from the Old French word "roi" meaning "king." It is believed to have originated in the Normandy region of northern France during the medieval period, around the 11th or 12th century.

One of the earliest recorded instances of the ROIS surname can be found in the Domesday Book, a comprehensive survey of land ownership commissioned by William the Conqueror in 1086. This suggests that the name may have been brought to England by Norman settlers after the Norman Conquest of 1066.

In France, the ROIS surname was often associated with individuals who held positions of authority or were closely linked to the royal court. Some early bearers of the name may have been officials or servants in the households of French monarchs.

During the Middle Ages, the ROIS surname was also found in various regions of France, including Brittany and the Île-de-France region around Paris. It is possible that the name was derived from place names containing the word "roi," such as Roye or Royat.

One notable individual with the ROIS surname was Jean ROIS, a French poet and historian who lived in the 15th century (c. 1420-1492). He is best known for his works chronicling the reigns of French kings Charles VII and Louis XI.

Another prominent figure was Nicolas ROIS, a 16th-century French scholar and theologian (c. 1510-1568). He was a professor at the University of Paris and played a significant role in the religious debates of the Reformation era.

In England, the ROIS surname can be traced back to the 13th century. One early record mentions a Robert ROIS, who was listed as a landholder in the county of Gloucestershire in 1273.

During the 14th century, a John ROIS was recorded as a resident of the village of Whittington in Shropshire, England, in 1327. This suggests that the name had become established in various parts of the country by that time.

In the 16th century, a notable bearer of the ROIS surname was Sir John ROIS, a member of the English gentry who served as a Member of Parliament for Taunton in Somerset during the reign of Queen Elizabeth I (c. 1540-1610).
