thod smyon bsam 'grub

second son of ma gcig lab sgron; together with his older brother rgyal ba don grub he became a lineage holder of his mothers teaching of gcod. He is not to be confused with his older brother's grandson of the same name. It is interesting to note that this second Thönyön Samdrub became the father of a daughter named lan thog ma, who was supposedly an emanation of ma gcig las sgron. This woman was also instrumental in the preservation and spreading of the teaching and lineage of Chod [TSD]
