The Midrash Genesis Rabbah 23:4 links Emzara to Naamah. Emzara is mentioned in the book of Jubilees, you then have to use the verse below to link Naamah to Cain. ButI am not sure if Emzara is Naamah based on a quick look.
(Edit: I forgot to point-out that the mid rash is jewish trash).
Gen 4:22 And Zillah, she also bare Tubalcain, an instructer of every artificer in brass and iron: and the sister of Tubalcain was Naamah.
From a Bible site
There does not seem to be any passages in the Bible referring to Noah's wife other than the account beginning in Genesis 7:7. It does not give her name, however, according to Jewish tradition her name is Naamah - the sister of Tubal-cain, a descendant of Cain, the son of Adam and Eve (see Genesis 4:22). Why Tubal-cain's sister (a daughter of Lamech by his wife Zillah) should be specifically mentioned is unknown. Jewish tradition made her Noah's wife. Her name, meaning "the beautiful" or "the pleasant one," reflects the worldly mind of the Cainites, who looked for beauty rather than for character as the chief attraction in women.
I don't think Noah would have been righteous if his wife was a canaanite.
