Haplogroup R-M405

What is Paternal Haplogroup R-M405?

Haplogroup R-M405, also known as Haplogroup R-M343 (Y Chromosome Consortium long-form label), is a genealogical group of lineages defined by unique genetic markers present on the Y-chromosome. Your paternal haplogroup, or that of your father if you do not have a Y-chromosome, paints a picture of your ancient origins and the migrations of your ancestors. Although your paternal haplogroup reflects just one of your many ancestral lineages, it carries information about that lineage over tens of thousands of years.

Haplogroup R-M405 is descended from haplogroup R-M343. Among 23andMe research participants, haplogroup R-M405 is commonly found among populations in the United Kingdom.

It's important to note that your haplogroup doesn't define your current ethnic identity; rather, it provides an insight into your deep ancestry on the paternal side.

Haplogroup R-M405 is 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.
