Yandyr
The Yandyr, also recorded as Yandygir, were a small Yukaghir clan group of the Yana and Omoloy country in the far northern Siberian tundra, closely bound to the Yandin and speaking the same Yan, or Detkil, variant of Yukaghir. Their shared name is traced to the Yukaghir word for a goose, or else to the local prince Uyanda.
Russian fur-tribute records of the mid-1600s list them among the stone Yukaghirs of the Lena-Yana tundra, a few hundred strong at most. Smallpox, feuds with Even and Evenki neighbors and the pressure of tribute broke the group up within a few generations, and its families were absorbed into the surrounding tundra peoples.
