Genetics Unveil the Genealogical Ancestry and Physical Appearance of an Unknown Historical Figure: Lady Leonor of Castile (Spain) (1256–1275)

[摘要] Through this study, it has been possible to establish an accurate prediction of the physical characteristics, biogeographical origin, and genealogical ancestry of a previously obscured historical figure: The Princess Lady Leonor of Castile (1256–1275), one of the legitimate daughters of the Spanish King Alfonso X “The Wise”. The genetic analysis of External Visible Characteristics in the mummified remains attributed to this Princess has allowed determining her origin by mitochondrial and nuclear DNA analysis, and her physical appearance for hair, eyes, and skin color by autosomal SNPs. The results show that the mummified remains correspond to a young European woman with black hair, green-hazel eyes, and white skin. Her physical appearance has not been possible to be compared with any pictorial source, but the biogeographical analysis results are consistent with the historiographic genealogical information.
