Kel Gres
The Kel Gres were a confederation of Tuareg clans in the Air Mountains of present-day Niger before the 17th century.
Around 1405 they joined the Kel Ayr and other groups in establishing the Sultanate of Agadez. In the 18th century Tuareg groups moved south into Air; by the century's end the more numerous Kel Owey had pushed the Kel Gres farther south.
