Surname

In many societies, a surname or family name is the mostly hereditary portion of one's personal name that indicates one's family. It is typically combined with a given name to form the full name of a person, although several given names and surnames are possible in the full name. In modern times most surnames are hereditary, although in most countries a person has a right to change their name. A surname may also be referred to as a last name, particularly in American English, but not all societies place them last; some cultures place them at the start of a person's name. The number of surnames given to an individual also varies: in most cases it is just one, but in Portuguese-speaking countries and many Spanish-speaking countries, two surnames (one inherited from the mother and another from the father) are used for legal purposes. Depending on culture, not all members of a family unit are required to have identical surnames. In some countries, surnames are modified depending on gender and family membership status of a person. Compound surnames can be composed of separate names. The use of names has been documented in even the oldest historical records. Examples of surnames are documented in the 11th century by the barons in England. English surnames began to be formed with reference to a certain aspect of that individual, such as their trade, father's name, location of birth, or physical features, and were not necessarily inherited. By 1400 most English families, and those from Lowland Scotland, had adopted the use of hereditary surnames. The study of proper names (in family names, personal names, or places) is called onomastics.
