The Y-Chromosome STRs Profile of Louis XVII (1785-1795?)

We have studied by SEM-EDX some hairs from a lock of hair of the King of France Louis XVI and Queen Marie-Antoinette ‘s children. Among these hairs, the blond hair number three is covered with skin-cells and dandruffs. The mtDNA haplogroup of dandruffs of this hair is that of Marie-Antoinette ; the Y-STRs profile of this hair is that of Louis XVI, previously known. Consequently this hair is one of Louis XVII, one of Louis XVI’s son.
