Noah's wife was descended from Cain. The accounts of her vary -- mostly she gets a pretty good rap, but not always. The consensus seems to be that she was at least, the best of a bad bunch. Her evil ancestry came through in a sense in one of her sons, Ham who fathered Canaan, the kid that Noah loathed so much when he hit the bottle - the kid responding by castrating his sozzled tormentor -- which finally got Noah's attention sufficiently to sober up and get off the booze.
Could be, but can't support with scripture. Real question why Canaan was blamed for his father's act (maybe of sleeping with Noah's wife?) Think Noah "not drunken as we suppose", like those in Acts2, because he didn't know about fermentation following the Flood had produced alcoholic grape juice...
Sounds like 100% mythology to me.. I agree about much more to the story than what appears, but don't see any profit in following your line of 'maybe'..
"The kid" had a thing for boats, having spent so much of his pregnancy while his mother was on the boat. His descendants have always had a thing for low lying land close to water, and running a trading business based on shipping -- something of a racial memory perhaps. They developed a mythology around their mythical bird, the Phoenix, and renamed themselves, the Phoenicians.
