Family names, also known as surnames, are inherited names that identify members of a family. They often reflect a person's ancestry, occupation, or geographical origin. For example, the surname Smith may indicate a historical connection to metalworking, while Johnson suggests "son of John." In many cultures, family names are passed down from one generation to the next, typically from parents to children. This practice helps to establish family lineage and can provide insights into a person's heritage. Different cultures have various traditions regarding the order and use of family names, such as patronymic systems in some Scandinavian countries.
