The Fugates of Troublesome Creek were an extended family in eastern Kentucky, famous because several of them were born with striking blue‑tinted skin caused by a rare inherited blood disorder, not by “being a different race” or anything supernatural.

Who the Fugates Were

  • The family traces back to Martin Fugate , a French immigrant (often described as an orphan) who settled near Troublesome Creek in eastern Kentucky around 1820.
  • He married a local woman, Elizabeth Smith, and both carried a rare recessive gene that, when inherited from both parents, caused their children to have blue skin.
  • Of their seven children, four were reportedly blue, and over generations the trait appeared repeatedly as Fugates and neighboring families intermarried in the isolated Appalachian community.

Why Their Skin Was Blue

  • The condition is called methemoglobinemia , in which an abnormal amount of methemoglobin (a form of hemoglobin) builds up in the blood, making the skin look blue or purple.
  • In the “Blue Fugates,” this was due to an inherited enzyme deficiency (often linked to the enzyme diaphorase or cytochrome b5 reductase) that prevents normal conversion of methemoglobin back to regular hemoglobin.
  • Aside from the skin color and some risk of low oxygen symptoms at higher levels, many affected family members lived otherwise typical rural lives.

Life in Troublesome Creek

  • The Fugates lived in a very remote part of Kentucky’s Appalachian mountains, where poor roads and geographic isolation meant families often married within the same small community.
  • That isolation kept the recessive gene circulating, so blue‑skinned children appeared in multiple generations around Troublesome Creek and nearby Ball Creek well into the 20th century.
  • Locally, people simply knew them as “the blue people,” and accounts describe them as poor but generally well‑regarded neighbors.

Medical Investigation and Treatment

  • In the 1960s, hematologist Madison Cawein III and nurse Ruth Pendergrass tracked down affected family members after hearing stories of “blue people” in the hills.
  • Cawein connected their condition to inherited methemoglobinemia and treated them with methylene blue , which quickly turned their skin to a more typical color by helping convert methemoglobin back to normal hemoglobin.
  • A landmark paper on the family’s condition appeared in the medical literature in the 1960s, and the story has since become a classic example used in genetics and biology classes.

Today and Cultural Legacy

  • As roads, mobility, and marriage patterns changed, the gene became less concentrated in the Troublesome Creek area, and obvious blue‑skinned descendants became rare by the late 20th century.
  • Modern descendants may still carry the gene without showing blue skin, or only have subtle signs like a bluish tinge to lips or nails in cold conditions.
  • The Fugates’ story remains a widely discussed “human genetics” case, showing how a recessive trait can become prominent in a small, isolated community and how careful medical investigation can solve what once looked like a mystery.

TL;DR: The Fugates of Troublesome Creek were a real Kentucky family whose unusual blue skin came from an inherited form of methemoglobinemia, amplified by generations of marriage within a small, isolated Appalachian community, and later studied and successfully treated by physicians in the mid‑20th century.
