Like all matters concerning the gods in the ancient near east, it's complex, and every answer has to be qualified. So apparently in some traditions, Baal was the son of Dagan (another fertility god), and in some the son of El (the head of the Canaanite pantheon, often identified with Yahweh even by orthodox Yahwists).
> often identified with Yahweh even by orthodox Yahwists
This seems totally unsurprising, given that the Old Testament freely uses both terms while insisting there is only one god. What else are orthodox Yahwists supposed to think?
Have you tried googling "baal son of el"? I have no idea on who Baal is, or El, but the discussion sparked my curiosity and that's all I needed to do in order to answer for myself the question "where are you getting this from?".
