Question

what is surname?whydo we have surname?​

Answer 1

a hereditary name common to all members of a family, as distinct from a forename or given name.

Surnames were originally added to people's first names to distinguish them from other people who had the same first name locally e.g. Robert the baker or Robert at the wood. ... Ironically the surname Telford is derived from a Norman nickname “taille fer,” meaning 'cuts iron', indicating a possessor of great strength.
