Mr Poops and Mrs Born Naked: the story behind strange Dutch surnames

What's in a surname?

Roll call: Mr Poepjes (Little Poops), Mrs Naaktgeboren (Born Naked), Mr Muis (Mouse), and Ms Gekkehuis (madhouse).

No, this isn’t a children’s picture book. These are very real Dutch surnames. So how exactly did our Dutch friends end up with them?

For most of the Middle Ages, the Dutch got by just fine without last names, according to Dr Bloothooft of Utrecht University.

You were Jan, son of Pieter. Anna by the mill. Willem from the dike. In small towns, everyone always knew who you were and where you lived.

It wasn’t until 1811 that last names became mandatory.

Enter Napoleon

When Napoleon Bonaparte took the Netherlands into the French Empire, he ordered all Dutch people to come up with a fixed last name.

It is impossible to draft soldiers or collect taxes from 15 Jans, all sons of Pieters, living in one village.

When Napoleon invaded the Netherlands, he didn’t just bring soldiers. He brought paperwork. Suddenly, people who had gone their entire lives without a last name were told they needed one. Immediately. Permanently. For official documents. The kind of name that would end up on passports. Most assumed the French wouldn’t be around long. So they treated it like a joke. Two hundred years later, those jokes are still printed on Dutch passports. Before 1811, most people in the Netherlands didn’t use fixed surnames. Identity was local and practical. You were Jan, son of Pieter. Willem from the dike. Anna by the mill. In small towns and villages, that was more than enough. Everyone knew who you were, where you lived, and who your family was. There was no reason for a permanent family name when your entire world fit within walking distance. Society functioned perfectly fine this way. Records were local. Taxes were local. Land was local. If you never moved and no one around you shared your exact situation, a last name was unnecessary. That changed when Napoleon absorbed the Netherlands into the French Empire. The French state ran on bureaucracy. Censuses. Conscription lists. Tax rolls. You cannot efficiently draft soldiers or collect taxes if half the population is named “Jan, whose dad was Pieter.” So in 1811, the government ordered everyone to register a permanent surname. One name. Written down. Forever. Many Dutch citizens complied… sarcastically. Some registered as Naaktgeboren, meaning “born naked.” Others chose Zondervan, literally “without a surname.” There were families who went with Poepjes, and yes, it means exactly what you think. Names like Rotmensen, Piest, and De Grootste were calmly entered into official records. Napoleon eventually fell. The French left. The names did not. They’re still inherited today. Still legal. Still appearing on résumés, mailboxes, and international passports. All because an emperor wanted order, and an entire country responded with humor. History is full of grand strategies. This one came with punchlines.

As Napoleon conquered Holland and Friesland, village nicknames became last names and legal obligations.

What the Dutch took as a joke (that explains the surname Piest) passed through the generations for centuries and is now visible on passports, licenses, and birth certificates.

Five ways to create a Dutch last name

For those who took the task seriously, surnames generally fell into five categories, each one a little snapshot of who someone was at the time.

  • Where you came from: De Vries (the Frisian), Van Asten (from Asten)
  • Where you lived: Van Dijk (from the dike), Van ‘t Klooster (from the monastery)
  • What you did: Bakker (baker), De Jager (the hunter)
  • Who your family was: Jansen (son of Jan), Sikkema
  • What you looked like: De Lange (the tall one), Rood (red)

The catch, as Dr Bloothooft notes, is that what was true for the original bearer didn’t have to apply to their descendants.

Jan Bakker may well have baked bread. But his great-great-grandson is a software developer in Amsterdam.
