The Moktsa incarnations are based at Katok Dorjeden, a major Nyingma monastery in Kham. Most sources list Rigdzin Namkha Chowang as the First Moktsa and have the treasure revealer Namcho Mingyur Dorje as a pre-incarnation of Namkha Chowang, but some identify Mingyur Dorje as the First, and Namkha Chowang as the Second.
