Is 'family name' the same as 'last name'?

In most Western naming conventions, yes. 'Family name' is the more formal or precise term, while 'last name' is common in everyday American English. However, in cultures where the family name comes first (e.g., Chinese), 'last name' is misleading.

What is the difference between a 'family name' and a 'maiden name'?

A 'family name' is a person's current surname. A 'maiden name' specifically refers to the family name a person (traditionally a woman) had before marriage.

Can a child have a different family name from their parents?

Yes, though it is less common. This can happen through legal name changes, adoption, or specific cultural or personal choices by the parents.

When should I use 'family name' instead of 'surname' or 'last name'?

Use 'family name' in formal, official, or cross-cultural contexts where clarity is essential, as it is the most unambiguous term. 'Surname' is standard in British English, and 'last name' is very common in casual American English.

Translation Traps (for Russian speakers)

Avoid translating directly as 'имя семьи' (which would mean 'the name of a specific family', like 'the Smiths').
The correct equivalent is 'фамилия'. Note that in Russian documents, the order is often 'Фамилия, Имя, Отчество' (Family name, Given name, Patronymic).

Common Mistakes

Using 'family name' to refer to a nickname for the family (e.g., 'The Smiths' nickname is 'The Smitties').
Confusing it with 'middle name'.
Incorrectly assuming the family name is always the father's name (increasingly, children may take the mother's name).
