They were Deucalion and Pyrrha.
The only two survivors from the flood sent by Zeus in Greek mythology are Deucalion and his wife, Pyrrha. They were warned by Prometheus and built an ark to survive the deluge. After the waters receded, they repopulated the earth by throwing stones over their shoulders, which transformed into people.
Survivors of what exactly?
Deukalion and Pyrrha were the famous King and Queen of Northern Greece--the regions of Opountian Lokris, Malis, Phthiotis and the Thessalian lands. They threw stones (the mothers bones) to repopulate the Earth with people.
There were several un-named but mortal survivors of the deluge loosed by Zeus, however the primary survivors were the titan Prometheus' son, Deucalion and his wife, Pyrrha, who both escaped by building a chest. Megarus, Zeus' son of a Sithnid nymph, also survived by swimming to the top of Mount Gerania. When the waters subsided, Deucalion sacrificed himself to Zeus, who sent Hermes to him to choose what he would, and he chose to get men. He threw stones behind him and they became men, while his wife's stones became women, thus repopulating the Earth.
There were only two (!) known survivors from Chelmno ... They are both dead now, so the answer to the question is none.

Deukalion and Pyrrha, originally, however others have been claimed as King Dardanos was said to have sought refuge on Mount Ida in the Troad, Kerambos was carried to the heights of Mount Othrys by the Nymphs, Megaros fled to Mount Gerana, Arkas and Nyktimos were preserved on Mount Kyllene in Arkadia, and the tribe of Parnassos fled to the heights above Delphoi.

Michael Podchlebnik and Szymon Srebrnik were the two survivors from Chelmno.
Chelmno was an extermination camp. There are only two known survivors.
Yes, Zeus. By him she had her only two children, the twins Artemis and Apollo.
1. Chaim Hirszman, who was murdered by Polish nationalists in 1946. 2. Rudolf Reger, who emigrated to Canada in 1947. These were the only known survivors from Belzec ... There are rumours that a further 4 or 5 people many have survived.
