Whose Name Is It?

Björk, the Icelandic singer, has a surname. Sort of.

Her full name is Björk Guðmundsdóttir. Her father is Guðmundur, so she is Guðmundur’s daughter. Her brother would be a Guðmundsson. If she has children, they won’t carry “Guðmundsdóttir” at all. They’ll take her first name, or their father’s.

That’s a patronymic system. Your second name isn’t a family label. It’s a sentence: whose child you are.

Iceland isn’t unusual. Ethiopia works the same way. Abiy Ahmed’s father is Ahmed, which is why the correct way to refer to him is Prime Minister Abiy, not Prime Minister Ahmed. Somali names go a step further: your given name, then your father’s, then your grandfather’s. Your name is three generations long, and it’s different from your brother’s children’s.

Before English speakers feel too settled about any of this, look at the phone book. Johnson was John’s son. Williams was William’s. Mac and Mc mean “son of”, O’ means “descendant of”, and the Norman Fitz is “son of” too. Fernández is Fernando’s son, and Ivanovich is Ivan’s.

We used to name people this way too. The difference is that, over time, we stopped updating it. Most English families had a fixed surname by around the 1400s. Parts of Wales kept “ap”, meaning “son of”, for centuries longer, which is how ap Hywel became Powell and ap Rhys became Price.

So a surname is really a frozen patronymic: a description of one ancestor that stopped being true a long time ago.

This matters because forms are designed in one system and filled in by people from another. A box that says “Surname” assumes everyone has one. When someone from a patronymic culture meets that box, someone has to decide what goes in it: the father’s name, the grandfather’s, or the whole lot. Different clerks in different decades decide differently.

The person hasn’t changed their name. The paperwork has changed its mind.

Every name follows a system. The trouble starts when the form only knows one.
