King Louis XVI of France from a genetic test on blood in a cloth purported to have been collected at his beheading and maintained in an ornate gourd decorated with French Revolution themes. Confirmation of this genetic profile requires testing of a known relative. The sample was tested at two laboratories with the same results. The sample is most consistent with G2a3b1a samples and contains unusually high, rare values for markers DYS385B and DYS458 in this haplogroup G subgroup. Subsequent testing in 2012 on a mummified head, purportedly that of King Henri IV of France, revealed that typing of a limited number of Y-STR's showed a Y-Dna haplogroup of G2a. Reported researchers: "Five STR loci [from the sample taken from the head] match the alleles found in Louis XVI, while another locus shows an allele that is just one mutation step apart. Taking into consideration that the partial Y-chromosome profile is extremely rare in modern human databases, we concluded that both males could be paternally related." The two French kings were separated by seven generations.
