Dorje Chang, Fa Zang's teacher, claims that he's the 3rd incarnation of the historical Buddha, the one that Buddhism is based on. But this Dorje Chang lineage isn't a lineage in the sense of The 14th Dalai Lama, or The 16th Karmapa. In those lineages there's a transmission of teachings, some real cultural functions, Wikipedia pages...
But this goes beyond the usual claiming of Rinpoche status, or saying that he's some long-forgotten Tulku, I'm not sure his claimed lineage* even exists or is in any way recognized by any of the major schools of Tibetan Buddhism.
I am not an expert on Buddhism in any way but many Internet buddhism commenters, who are not affiliated with Dorje Chang, claim that Dorje Chang made up his lineage.
