The Town That Was Never There: How Trap Streets and Paper Towns Can Mislead Your Genealogical Research

The Town That Was Never There: Have you ever found a record for an ancestor living in a town that simply doesn’t exist? You’ve checked the census, you’ve looked at the land deeds, and you’ve stared at a beautiful 19th-century map, but when you drive to the location today, there’s nothing but an empty field or a highway bypass. Before you assume your ancestor lived in a “Brigadoon” style disappearing village, you might have fallen victim to a clever bit of cartographic trickery.

In the world of map-making, things aren’t always what they seem. For centuries, cartographers have been intentionally lying to us. They’ve inserted fake streets, non-existent towns, and imaginary mountains into their work. These are known as trap streets, paper towns, or copyright traps. While they served a specific purpose for the map-makers, they have created a massive headache for modern genealogical research.

The Secret World of Cartographic Traps

To understand why a map would lie to you, we have to look at the business of cartography. Making a map is an incredibly labor-intensive and expensive process. Historically, it required physical surveys, meticulous drafting, and deep geographic knowledge. Because the data was so valuable, other companies were often tempted to “borrow” (or flat-out steal) the work of a competitor rather than doing the survey work themselves.

To catch these thieves, cartographers began inserting tiny, intentional errors into their maps. If a competitor published a map featuring a fake street name or a non-existent village that only existed in the original creator’s imagination, the original maker had “smoking gun” evidence of copyright infringement.

Why Cartographers Planted “Paper Towns”

• Proof of Authorship: A unique, fake location acts as a digital—or in this case, analog—watermark.

• Asset Protection: It discouraged low-cost competitors from undercutting the prices of original surveyors.

• Legal Leverage: In an era before complex digital rights management, a fake town was the most effective way to win a court case against a plagiarist.

The Famous Case of Agloe, New York

Perhaps the most legendary example of a “paper town” is Agloe, New York. In the 1930s, Otto G. Lindberg and Ernest Alpers of the General Drafting Company created the name “Agloe” by combining their initials. They placed this fictional hamlet at a dirt road intersection in the Catskills on their Esso gas station map.

A few years later, the famous map-making giant Rand McNally published a map featuring Agloe in the exact same spot. Lindberg and Alpers thought they had caught them red-handed. However, the story took a bizarre turn. Rand McNally argued that the town did exist because people had seen “Agloe” on the Esso map, gone to that spot, and built a general store called the Agloe General Store. The fake town had literally been conjured into reality by the map itself!

Other Notable Examples of Fake Places

Several invented places have become minor celebrities in the worlds of cartography and local history, and some can easily intersect with genealogy research. Well‑documented examples include:

• Argleton, Lancashire: A “town” that appeared in Google Maps and Google Earth near the A59, spawning real estate listings, weather reports, and local directory entries for a place that turned out to be an empty field.

• Beatosu and Goblu, Ohio: Two phantom settlements added as a personal joke and subtle signature referencing university football rivalries, which still show how easily a map can record places that never actually existed.

Among printed road atlases, examples like La Taza Drive in California and other short, dead‑end streets in U.S. city guides have been cited as likely trap streets inserted to catch plagiarists. For a genealogist focused on address‑based research in those cities, such features can be tempting but misleading clues.

How Fictional Locations Sabotage Genealogical Research

For those of us building a family tree, maps are essential primary sources. We use them to plot where an ancestor’s farm was located, identify the nearest parish church, or understand the migration routes our families took. When a map contains a “trap,” it can lead a researcher down a very long and very frustrating rabbit hole.

The “Ghost Town” Wild Goose Chase

Imagine finding a family Bible entry stating a child was born in “Beatosu, Ohio.” You find Beatosu on a 1920s Michigan map. You spend weeks looking for vital records, cemetery listings, or local newspapers for Beatosu, only to eventually discover that “Beatosu” was a trap created by the Michigan State Highway Department (referencing “Beat OSU”). Your ancestor likely lived in a neighboring township, but the fictional name on the map sent your research off the rails.

Errors in Land and Property Mapping

Genealogists often use plat maps to see who lived next door to their ancestors. If a map-maker inserted a “paper” road or boundary to protect their copyright, it can make it appear that two families were neighbors when they were actually separated by significant terrain or distance. This can lead to incorrect assumptions about social circles, potential witnesses on documents, or even the identity of a spouse from a “neighboring” family.

The Problem of Modern Digital Maps

Don’t think this is just a problem with 1800s paper maps. Modern digital services like Google Maps have been caught using trap streets. In 2008, “Argleton” appeared on Google Maps in Lancashire, England. It didn’t exist in the real world, but it appeared in real estate listings and job postings because those services used Google’s data. If a future genealogist looks back at 2008 data, they might spend years trying to find the “Argleton branch” of their family tree.

How to Identify a Map Trap in Your Research

So, how can you tell if that obscure village in your great-grandfather’s county is a real place or a cartographer’s prank? Here are some strategies to verify your locations.

• Cross-Reference with Census Data: If a town appears on a map but never appears as a district or locality in the Federal or State Census, it is a major red flag.

• Check the US Post Office Records: The Post Office Department kept meticulous records of every post office location. If your “town” never had a post office or a Rural Free Delivery route, it might be a paper town.

• Examine Multiple Map Publishers: Compare maps of the same area from different companies (e.g., Sanborn, Rand McNally, and local county surveyors). If a location only appears on one specific brand of map and disappears in later editions, it’s likely a trap.

• Search the USGS Geographic Names Information System (GNIS): This database is the official repository of domestic geographic names. It often includes “historical” entries that can clarify if a place name was a legitimate settlement or a “variant” name.

• Look for Unusual Names: Many trap streets or towns use anagrams of the map-maker’s name or inside jokes (like the “Beatosu” example). If a name sounds remarkably modern or out of place for the local dialect, investigate further.

Practical Implications for Family Historians

When you encounter a location that seems to vanish from the face of the earth, don’t delete your notes immediately. These “ghost” locations actually tell us something about the sources we are using.

Assessing Map Reliability

If you find a trap street on a historical map, it tells you that the map-maker was likely a commercial entity rather than a government surveyor. Commercial maps (like those sold for travelers or gas stations) are far more likely to contain fakes than official government topographic surveys or military maps.

Understanding the “Neighborhood” Context

If you realize a road on a map is a trap street, you can re-evaluate the proximity of your ancestors to local resources. Was that “shortcut” to the mill actually there? If not, your ancestor had to travel a different route, perhaps passing a different church or store where they might have left a paper trail.

Conclusion: Don’t Let the Map Fool You

Maps are more than just guides; they are historical documents with their own biases, errors, and secrets. As genealogists, we have to approach them with the same critical eye we use for a family legend or a questionable death certificate. The next time you find a location that doesn’t seem to fit, remember the story of Agloe and the “trap streets.”

Understanding the motivations of the cartographer helps us become better researchers. It reminds us that our ancestors didn’t live in a vacuum—they lived in a world that was being mapped, measured, and sometimes manipulated for profit. By learning to spot these “paper towns,” you ensure that your family history stays grounded in reality, rather than lost in a cartographic trap.
