Blue People

The Fugates, a family that lived in the hills of Kentucky, are the most famous example of this hereditary genetic condition. They are known as the "Blue Fugates."[10] Martin Fugate settled near Hazard, Kentucky, circa 1800. His wife was a carrier of the recessive methemoglobinemia (met-H) gene, as was a nearby clan with whom the Fugates intermarried. As a result, many descendants of the Fugates were born with met-H.
