Yesugei

Yesugei or Yesükhei Baghatur (c. 1134–1171) was a major chief of the Khamag Mongol confederation and the father of Temüjin, who later became known as Genghis Khan. Yesügei was from the Borjigin family, and his name means "like nine", meaning he had the auspicious qualities of the number nine, a lucky number to the Mongols.
