Norman surnames originated from the Normans, a group of people descended from Vikings who settled in Normandy, France. After the Norman Conquest of England in 1066, many Normans adopted surnames based on their locations, occupations, or personal characteristics. Common examples include names like Duke, Baker, and Smith. These surnames often reflect the feudal system established by the Normans, where land ownership and titles were significant. Over time, many Norman surnames spread across Europe and evolved, influencing the development of surnames in various cultures. Today, they remain an important part of genealogical studies and cultural heritage.
