Why do people have names? Here is the answer.

People place names with purposes of identification and to speak culturally. In early primitive societies, people usually had only one name to identify themselves, since the population was very small.

As the population in various areas increased, people began using a second name or an surname to identify themselves.

One way to identify yourself was to use the wording by referring to the individual and his work. For example: “Harold Farkator” or “Eric Red (red)” are names that describe the profession or refer to the color of hair/lax, etc.
Similarly, the history of family surnames or names refers to an individual's father's name.

Usually, a boy, especially in Great Britain and in many other parts of the world (but most rarely in Albanian areas), can be referred to by the name given to him, followed by his father's name, such as “Harold, son of Erict” or “Harold Eric” (Eric+ Son/ Son=boy).
