Surnames, also known as family names or last names, are an important part of our identity. They often indicate a person's heritage or family lineage. For example, the surname Smith may suggest that an ancestor worked as a blacksmith, while Garcia can indicate Spanish origins. Surnames help distinguish individuals with the same first name and are used in formal settings, like on legal documents. In many cultures, surnames are passed down from parents to children, creating a sense of belonging and continuity. Some people may choose to change their surname for various reasons, such as marriage or personal preference. Understanding surnames can provide insights into history and family connections.
