In recent years there has been a trend towards equality of treatment in relation to family names, with women being not automatically required or expected, or in some places even forbidden, to take the husband's surname on marriage, and children not automatically being given the father's surname.
In this article, family name and surname both mean the patrilineal surname, handed down from or inherited from the father's, unless explicitly stated otherwise.
This practice also differs between cultures; see T–V distinction.
In English-speaking cultures, family names are often used by children when referring to adults but are also used to refer to someone in authority, the elderly, or in a formal setting, and are often used with a title or honorific such as Mr., Mrs., Ms., Miss, Doctor, and so on.
