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 the nomadic Tuareg of the Sahara

Though haplogroup H1 rarely reaches high frequencies beyond western Europe, over 60% of eastern Tuareg in Libya belong to haplogroup H1. The Tuareg call themselves the Imazghan, meaning “free people.” They are an isolated, semi-nomadic people who inhabit the West-Central Sahara and are known today for a distinctive dark blue turban worn by the men, and for their long history as gatekeepers of the desert.How did women carrying H1 make it all the way from western Europe to this isolated community? They likely migrated from Spain across the Strait of Gibraltar into Morocco after the Last Ice Age, where they were assimilated into the Berbers of the Mediterranean coast. Then, about 5,000 years ago, the Sahara shifted from a period of relative habitable conditions to its dramatically arid desert environment. This shift may have caused migrations throughout the Sahara, prompting the ancient Tuaregs to meet and mingle with the Berbers, bringing H1 lineages into their population.

What do people with the surname Brook have in common?

Spoiler alert: it's complicated. People with the same last name are usually no more genetically similar than a randomly sampled group of people from the same population.
