Here’s something wild about old Frisian culture: your last name wasn’t necessarily permanent. It could change based on where you moved.
I’m not talking about immigration or marriage. I’m talking about literally moving to the next village and getting a new surname to match.
Before the 1800s, many Frisians used what linguists call “locative surnames.” Your family name told people where you lived, not who your ancestors were. Move to a different farm or village? Congratulations, you got a new name.
So Jan living at the farm called “Hemmema” would be Jan Hemmema. If Jan moved to a place called “Sijperda,” he’d become Jan Sijperda. Same guy, different address, different surname.
This drove record-keepers absolutely insane.
Church officials trying to track births, deaths, and marriages would find the same person listed under three different surnames across their lifetime. Genealogists today still have nightmares about this.
The system made perfect sense to Frisians, though. In a rural province where everyone knew everyone, your location mattered more than your lineage. Saying “Jan from Hemmema” immediately told people which Jan you meant, because there were approximately seven thousand Jans.
Some families had both types of surnames running at the same time. You might have a patronymic (father’s name plus -ma or -stra) and a locative surname, and you’d use whichever one made sense in context. Super helpful for everyone involved.
The French showed up during the Napoleonic occupation and absolutely lost their minds at this system. They demanded everyone pick ONE surname and stick with it. Forever. Non-negotiable.
This is why Frisian surname registration in the early 1800s is such a mess. Some families picked their locative name. Others picked their patronymic. Some apparently just shrugged and made something up on the spot.
You can still spot these old locative surnames today. They often end in -ma, -stra, -ga, or -um. Names like Boomsma (from Booms), Steenstra (from Steens), or Banga (from Bant) all point to specific places.
The -ma and -stra endings are classic Frisian markers. In fact, if you meet someone with a surname ending in -ma or -stra, there’s a very good chance they have Frisian ancestry, even if they’ve never set foot in Friesland.
These endings originally meant “the people of” or “those living at.” So Hemmema literally meant “the Hemme people” or “those from Hemme.” It was a group identifier that became a family name almost by accident.
Some of these place-based surnames are incredibly specific. Onderdendam means “under the dam.” Terlouw means “at the shelter.” Vanderwal means “from the wall.” These names are like little GPS coordinates frozen in time.
The really confusing part? Some of these place names don’t exist anymore. The farms got renamed, merged, or disappeared entirely. So you’ve got families carrying surnames that reference locations no historian can actually find.
Dutch surnames work differently. Most Dutch people got stuck with patronymics (van der Berg, de Vries) or occupational names (Bakker, Smit). The Frisian system of fluid, location-based naming was pretty unique, even within the Netherlands.
This naming flexibility shows something important about Frisian identity. It wasn’t about bloodlines or family dynasties. It was about community and place. Where you belonged mattered more than who your great-grandfather was.
Today, these surnames are permanent. The Boomsmas of Amsterdam aren’t changing their name even though they’re nowhere near Booms. But the names still carry that old Frisian logic: identity tied to geography.
If you’re researching Frisian genealogy, this locative surname system is either your best friend or your worst enemy. It gives you amazing clues about where families lived. But it also means the same ancestor might appear under completely different names in different records.
Good luck explaining to your DNA match why your shared great-great-grandfather has three surnames in the church records.
The Frisian approach to names reveals something about how they saw themselves. Not as fixed lineages stretching back through time, but as people rooted in specific places. The land shaped the name, not the other way around.
It’s one more way Frisian culture did things differently. Even something as basic as your family name followed its own peculiar logic.
