Ever heard of Troublesome Creek? It’s a quiet spot in Perry County, Kentucky. For over a century, if you wandered up those hollows, you might have bumped into someone whose skin was the color of a bruised plum or a clear summer sky.
They weren't aliens. They weren't wearing makeup. They were just the blue people of Appalachian lore, a family that carried a secret in their blood for generations.
Most folks assume it’s a tall tale, like Paul Bunyan or Mothman. But the "Blue Fugates" were very real. It’s a story about isolation, a rare genetic fluke, and the kind of deep-seated mountain resilience that defines Eastern Kentucky. Honestly, the science behind it is just as wild as the legends.
The Frenchman and the Redhead
It all started back in 1820. Martin Fugate, a French orphan, hopped across the pond and settled on the banks of Troublesome Creek to claim a land grant. He was, by all accounts, blue. Not "sad" blue—physically, indigo-skinned blue.
Now, imagine the odds.
Martin married a local woman named Elizabeth Smith. She was pale, red-headed, and looked perfectly "normal." But here is the kicker: by a one-in-a-million stroke of genetic bad luck, Elizabeth carried the exact same recessive gene for a rare condition called methemoglobinemia.
They had seven kids. Four of them were blue.
Because the area was so isolated—we're talking no roads, no rails, just steep hills and thick forest—the family stayed put. They intermarried with the neighbors. Combs, Smiths, Ritchies, and Stacys. When you live in a "hollow" (pronounced holler by the locals) and the next town is a day's ride away, your dating pool is pretty shallow. This kept the recessive gene circulating in the local gene pool for over 150 years.
Why Were They Actually Blue?
Let's get into the weeds of the biology here because it’s fascinating.

Usually, your blood is red because hemoglobin carries oxygen. But if you have methemoglobinemia, your blood contains an abnormal amount of methemoglobin. This version of the protein is great at holding onto oxygen but terrible at releasing it to your tissues.
The result?
The blood becomes a dark, chocolatey brown color. When that brown blood flows through the veins of a fair-skinned person, it reflects through the skin as a distinct, startling blue.
For the blue people of Appalachian communities, this wasn't really a health crisis. Most of them lived long, healthy lives. They farmed, they raised kids, they reached their 80s and 90s. They were just... blue.
The local community in Perry County was actually pretty protective of them. While outsiders might have stared or whispered about "blood kin," the locals just saw them as neighbors. "They're just the blue Fugates," folks would say. It was a matter of fact, not a circus act.
Dr. Madison Cawein and the "Cure"
Fast forward to the early 1960s. A hematologist named Dr. Madison Cawein at the University of Kentucky heard the rumors. He was a bit of a medical detective, and he trekked up to Hazard, Kentucky, to find them.
He eventually met Patrick and Rachel Ritchie.
"They were bluer than hell," Cawein later remarked. He could see they were embarrassed by the attention, but they were also tired of the stigma. Imagine going to town and having people think you're suffocating or heart-sick just because of your face.

Cawein did some digging. He realized they lacked an enzyme called diaphorase. Without it, their bodies couldn't convert methemoglobin back into oxygen-carrying hemoglobin.
He had a crazy idea. He wanted to use methylene blue.
Yes, he wanted to inject blue dye into blue people to turn them pink. It sounds like something out of a cartoon. But the chemistry was sound. Methylene blue acts as an electron donor, helping the body "reset" the blood.
He tried it on Patrick and Rachel. Within minutes, the blue faded. For the first time in their lives, they saw their skin turn a healthy pink. They were ecstatic. Cawein even gave them a supply of methylene blue tablets to take like vitamins, which kept the blue at bay as long as they stayed consistent with the pills.
Is the Blue Gene Still Around?
By the mid-20th century, the isolation of the Appalachians began to crumble. Coal mines brought in new workers. Roads were paved. People moved away to the cities.
The "blue" gene is recessive. That means both parents have to carry it for a child to show the trait. As the Fugates and their relatives started marrying people from outside the hollows—people who didn't carry that specific mutation—the blue skin began to disappear.
The last "famous" blue person was Benjamin Stacy. Born in 1975, he came out of the womb almost purple. Doctors were terrified and rushed him to the University of Kentucky Medical Center for a transfusion.
But his grandmother spoke up. She told the doctors about the "blue Fugates" of Troublesome Creek.

As it turned out, Ben only had one copy of the gene, or his body was just slightly less efficient at birth. Within a few weeks, he lost the blue tint, though his fingernails and lips would still turn blue whenever he got cold or angry. Today, the trait is largely dormant, hiding in the DNA of descendants who look like anyone else on the street.
Beyond the Skin: The Reality of Appalachian Life
It is easy to turn this into a "freak show" story, but that does a disservice to the people who lived it. The blue people of Appalachian history were a product of geography as much as biology.
Eastern Kentucky has always been a place of intense beauty and intense hardship. The Fugates weren't "inbred" in the way Hollywood movies like Deliverance portray mountain people. They were a family caught in a geographic trap.
If you look at the research by Dr. Cawein or the family trees mapped out by historians, you see a story of survival. They built lives in a place where most people couldn't. They survived the Civil War, the Great Depression, and the collapse of the timber industry.
The "blue" was just a quirk. A biological footnote in a much larger story of Kentucky's mountain culture.
What This Teaches Us Today
There are a few big takeaways from the Fugate saga that apply to modern health and genetics:
- Genetic Diversity Matters: Small, isolated populations are prone to rare conditions. This isn't just about skin color; it's why certain communities have higher rates of specific cancers or metabolic disorders.
- The Power of Rare Disease Research: Dr. Cawein's work didn't just help the Fugates. It helped map out how enzymes interact with our blood, which has implications for treating toxic exposures and other blood disorders.
- Stigma is Social, Not Biological: The Fugates were healthy. Their "disability" was entirely based on how others perceived their appearance.
Actionable Steps for Exploring This History
If you're interested in the real history of the Fugates and the science of the "blue" people, don't rely on TikTok rumors. Here is how to get the real story:
- Visit the Harry M. Caudill Memorial Library: Located in Whitesburg, KY, it holds significant genealogical records for the families of the Kentucky River area.
- Read "The Science of the Blue Fugates": This seminal 1982 article by Cathy Trost in Science 82 magazine remains the gold standard for the medical history of the family.
- Explore the Bobby Davis Museum: Situated in Hazard, Kentucky, this museum offers context on the life and culture of Perry County during the era when the Fugates were most prominent.
- Check Your Own Genetics: If you have ancestors from the Perry or Knott County areas and notice a tendency for your lips or nails to turn blue in the cold (more than the average person), you might be a carrier of the diaphorase deficiency. It’s worth mentioning to a doctor, though generally harmless in carriers.
The story of the Fugates is a reminder that the world is much weirder and more wonderful than we usually give it credit for. Sometimes, the most unbelievable legends are actually backed by a simple drop of brown blood.
