Sochigel

Sochigel (Modern Mongolian: Сочигэл, Russian: Сочихэл, Chinese (Simplifed): 速赤格勒) was either a junior wife or concubine of Yesügei, the chief of the Khamag Mongol confederation and father of Genghis Khan. Sochigel's children were Ghengis Khan's half-siblings, and included Behter and Belgutei; the latter became one of Genghis Khan's advisors.
