The Oxford Ancestors diagram showing the Seven Daughters of Eve Clans. From one woman named Hélèna, by Bryan Sykes the author of The Seven Daughters of Eve, 45% of all present day western Europeans have descended. Hélèna lived 20,000 years ago somewhere in the Dordogne River Valley in south central France. My subclan is shown by the star. I am two muttions different from the original Hélèna. The locations of my mutations are shown by the red Cs on the DNA chart at the bottom of the chart.
