Both my maternal and paternal families have American roots deep in Appalachian Kentucky - my paternal family hails specifically from the Cumberland Gap in the Appalachian mountains where old ancestral ways still flourish among the mountain folk. My maternal family came to Illinois from Joy, Kentucky in the late 1800's or early 1900's.
Also from Appalachian Kentucky, the indigo blue-skinned Fugate family shares a common genetic ancestry with myself and my family. Fugate is a name with origin in Alsace, a region located on the eastern border of France and on the western bank of the Rhine (adjacent to Germany). Alsatian Fugates emigrated from Alsace first to the UK, then to the United States, and then through the Appalachian Mountains into Kentucky. This is also the emigration route of my genetic Clan Woden (I Y-DNA Haplogroup) paternal ancestors from Europe to the United States.
My father's I2 (I-M223, subbranch I-Z166, subbranch I-S20905, subbranch I-Z190, subbranch I-Y20888) genetic fatherline has scientifically documented roots through Alsace. Eupedia on the I2-I-M223 haplogroup informs us that:
"The I-S20905 transition is found in Germany (Rhineland), France (Alsace), Switzerland, Hungary, as well as England, Sweden and Finland. The continental group (Z190+, which my father is) might descend from the Alemanni, Suebi or another Germanic tribe that settled around Swabia."
I personally have scientifically documented autosomal genetic matches in all of these areas, as well as does my father's ancestral genetic fatherline. The region of Alsace was conquered by a Germanic tribe connected to my indigenous Old European-Germanic paternal fatherline in the 5th century CE. It is quite possible then that I carry a recessive gene for blue skin, one inherited from my father.
Blue skin is rare in modern populations due to the recessive nature of the trait. A recessive trait requires two copies of the gene (one from the father and one from the mother) to be present in an individual for the trait to be phenotypically expressed (to manifest as blue skin). We inherit half of our father's genes and half of our mother's genes. Blue skin was phenotypically expressed among many members of the Fugate family due a high level of clan inbreeding.
Indigo blue skin is a trait many Aryan-Hindu deities manifest in their human forms. In traditional Hindu religion, the blue skin of the deities in human form is not thought to be symbolic or artistic. It is thought to be the true complexion of the deity manifest in human form. As with the Appalachian clans of Kentucky, blue skin was also likely phenotypically expressed among the ancient Aryan clan of India due to a high level of clan inbreeding (making it more likely that an individual might possess two copies of the gene). Similarly as among the Fugate family, some Hindu deities in human form have blue skin (two copies of the gene) while some deities in human form have white skin (one copy of the gene).
People with these genes have varying levels of methemoglobin, an unusual type of hemoglobin molecule, in red blood cells. The Fugates lived well into their 80's and 90's without any significant health problems.
