Olga Dmitrievna Kudrina (c. 1890-1944) was a shamaness among the Reindeer Evenki of northern Inner Mongolia along the Amur River's Great Bend (today under the jurisdiction of Genhe, Hulunbuir).
[5] Kudrina's responsibilities as a shamaness included aiding in the hunt, curing the sick, and watching over the souls of the deceased; she was required to be knowledgeable about spirits and religion.
This meant that she had to make arduous treks over the Greater Khingan mountains to reach the hunting grounds of the Mohe group.
[9] Kudrina died later that same year, leaving behind two other shamans: her cousin Kudrin, and Njura Kaltakun, neither of whom had widely accepted authority among all the groups.
[13] She also took Anatolij Makarovič Kajgorodov (1927–1998), a member of a Russian Cossack family with whom the Reindeer Evenki frequently traded, as a godson; he would go on to become a well-known ethnographer of the Tungusic peoples.
