His mtDNA HVR1 and HVR2 profile was derived from DNA testing of a piece of his own heart tissue, ancient hair samples from his mother (Marie Antoinette) and two of his maternal aunts, and from samples collected from two living maternal line descendants of Maria Theresa – Queen Anne of Romania and André de Bourbon Parme.
