Your paternal lineage may be linked to King Louis XVI

The rule of France by men of the House of Bourbon began with King Henri IV in 1589 C.E. and continued until the beheading of his direct paternal descendant King Louis XVI in 1793. Several years ago, researchers analyzed a mummified head and a blood-soaked cloth that they believed might belong to the two kings, and concluded that the royal paternal line belonged to haplogroup G. In a more recent study, however, a different set of researchers tested three living men who are direct descendants of the Bourbon kings. Their efforts revealed that the male lineage of the House of Bourbon is actually a branch of haplogroup R-M405.

Your maternal lineage may be linked to Marie Antoinette

Because it is so dominant in the general European population, haplogroup H also appears quite frequently in the continent's royal houses. Marie Antoinette, an Austrian Hapsburg who married into the French royal family, inherited the haplogroup from her maternal ancestors. So did Prince Philip, Duke of Edinburgh, whose recorded genealogy traces his female line to Bavaria. Scientists also discovered that famed 16th century astronomer Nicolaus Copernicus traced his maternal lineages to haplogroup H.
