7 women
How names are in our genes » "[...] As a result, Sykes has been able to trace the webs of family links back to seven women, whom he calls the founding mothers of Europe. He has named them Ursula, who lived in Greece 45,000 years ago; Xania, Ukraine 25,000 years ago; Helena, from South-west France 20,000 years ago; Velda, from northern Spain 17,000 years ago; Tara, from northern Italy 17,000 years ago; Katrine, from eastern Italy 15,000 years ago; and Jasmine, from Syria 10,000 years ago." I wonder from whom I am a descendant.
