Noah and his wife Emzara (name according to tradition)
Shem and his wife Sedegetelebab (name according to tradition)
Ham and Ne'elatama'uk (name according to tradition)
Japheth and 'Adataneses (name according to tradition)
The lineage of Cain allegedly survived through the wife of Ham, Ne'elatama'uk, who was allegedly of Cainite ancestry.
Of course, these are all only traditions. The only truth that Christians know is that there are eight persons in the ark, Noah, Shem Ham, and Japheth, and the wives of the four men, who are not named.
