Deed research can be mind-numbingly tedious—page after page of “whereas” and “heretofore,” enough legal jargon to make your eyes cross. But every now and then, you strike gold. Today’s discovery came buried in a dusty 1839 land transaction that finally explains one of Florence, Missouri’s most puzzling mysteries: Why does the town’s historic plat map look like it was drawn by someone who couldn’t count?
The Puzzle That Stumped a Town
For decades, residents of Florence have scratched their heads over their town’s original layout. Early historians, including my grandmother Roma, believed Florence was founded around 1832 by a mysterious Mr. Williams. That theory held water until researchers for the 2022 Florence History book did what historians do best: they dug deeper into the deeds. What they found wasn’t just a correction to local lore—it was a geographic riddle that had been hiding in plain sight for over 180 years.
Look at Florence’s earliest surviving plat map, drawn February 24, 1860, and you’ll spot the problem immediately. Among rows of neat, uniform 50-foot lots sits a collection of irregularly shaped parcels that seem to follow no pattern whatsoever. Most puzzling of all: Block D contains not one, but two lots numbered 10. In a world where property boundaries mean everything, having duplicate lot numbers should be impossible.
So what happened? The answer lies in a tale of frontier ambition, early settlement, and one man’s stubborn refusal to conform to someone else’s grid.
Following the Paper Trail
Morgan County genealogists caught a lucky break when it comes to early records. While a courthouse fire consumed Deed Book One in the county’s early years, the indexes survived, providing crucial breadcrumbs for researchers willing to follow them.
The trail begins with William Norton, who received the first official land patent for what would become Florence on November 2, 1837—80 acres described in the government’s precise language as “the West half of the SE quarter of Sec 11 Twp 44 R 19.” But Norton wasn’t just accumulating farmland. He had bigger plans. 
The Real Founder Emerges
Norton, it turns out, was Florence’s true founder—not the mysterious Williams of local legend. But Norton was also a pragmatist. He knew that to create a successful town, he needed to attract settlers and businesses. So he laid out his town at the intersection of two well-used “roads” and began selling lots even before the official town plat was completed and filed.
Enter John Porter, a man who would inadvertently create a cartographic headache that would puzzle residents for nearly two centuries.
When Informal Becomes Permanent
By August 29, 1839, when Porter decided to sell his Florence holdings to Daniel Hord, the transaction revealed something remarkable. The deed describes three parcels: “Lot No Eight (8) Lot No nine (9) and the Lot marked Porter“—not Lot 10, but simply “the Lot marked Porter.”
This wasn’t sloppy record-keeping. It was the result of organic town development clashing with formal surveying. Porter, a farmer on all available census records, had not likely been living on his lot, but the land that lay at the corner of the intersecting trails may have had a store or trading post even before anyone bothered to assign it an official number. When the time came to create the formal plat map, the surveyor faced a dilemma: Porter’s lot was already there, already established, already occupied. It couldn’t simply be erased to make room for a neat, numbered grid.
The $250 Solution
The deed between Porter and Hord tells the whole story in beautifully precise 19th-century legalese. For $250—a substantial sum in 1839—Porter sold three adjacent lots that together formed an irregular parcel “fronting on main street sixty feet and fronting on Columbia Street one Hundred and ninety-five feet, and fronts on Royal Street sixty feet.”

Notice that description: this isn’t a standard rectangular lot. It’s a custom-shaped parcel that reflects the reality of early settlement patterns, where people claimed land based on practical considerations rather than surveyor’s grids.
The Mapmaker’s Compromise
When the official plat was finally drawn in 1860, the surveyor chose an elegant solution to an impossible problem. Rather than renumber the entire block or leave gaps in the sequence, he simply created two Lot 10s. One for the standard grid system, and one to acknowledge Porter’s pre-existing claim.
It’s a perfect example of how American frontier towns developed organically, with formal systems adapting to informal realities rather than the other way around.
Research Tips for Modern Genealogists
This discovery offers valuable lessons for anyone researching early American settlements:
- Start with the anomalies. When you see something that doesn’t make sense on a historical map or document, don’t assume it’s an error. Often, these irregularities tell the most interesting stories.
- Follow the money trail. Land transactions reveal not just who owned what, but how communities actually developed. The price Porter received—$250 for three lots in 1839—suggests Florence was already a thriving concern, not a speculative venture.
- Don’t ignore “boring” legal documents. The deed between Porter and Hord reads like typical 19th-century legal boilerplate, but embedded within all that formal language are clues about how people actually lived and worked.
Modern Research Tools
Today’s genealogists have advantages our predecessors couldn’t imagine. Morgan County’s early deed books (through #33) were microfilmed decades ago, and FamilySearch’s Full-Text Search tool has revolutionized the process. You can now search for specific names, dates, or even legal descriptions across thousands of pages in minutes rather than days.
For hands-on researchers, the Morgan County courthouse in Versailles, Missouri offers a well-organized research room with helpful staff. But whether you visit in person or search online, the key is understanding the historical context that shaped these documents.
The Bigger Picture
The story of Florence’s two Lot 10s is really a story about American community building. Our ancestors weren’t just buying and selling land—they were creating places where families could put down roots, start businesses, and build futures. Sometimes that meant bending the rules, ignoring the grid, and making practical compromises that would puzzle future generations.
John Porter (1802-1860) probably never imagined that his informal lot designation would survive on maps for nearly two centuries. But his stubborn refusal to conform to someone else’s numbering system preserved a piece of Florence’s authentic founding story.
The next time you encounter an old map or document that seems to make no sense, remember Florence’s dual Lot 10s. Sometimes the most confusing details hide the most human stories—tales of real people making practical decisions in an imperfect world, leaving behind puzzles that take generations to solve.
Best of luck finding solutions to your Lot 10s!
