Your paternal lineage may be linked to early European farmers
If you have haplogroup E1b1b1, your paternal line stems from a branch of E-M215 called E-M5021. Men bearing this lineage migrated from the Balkans to southwestern Europe during the spread of agriculture by early farmers in the agricultural revolution, which began about 10,000 years ago in the Fertile Crescent. Early members of haplogroup E1b1b1, some of the world's first farmers, had a competitive advantage over native men, who didn't have farming technology. As a result of this advantage, haplogroup E1b1b1 became widespread and populous during the agricultural revolution. The effects of this ancient advantage are still seen today, with haplogroup E1b1b1 being represented from Portugal and Spain to Palestine, southern Africa, and Russia.
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.
