There is currently no ingame documentation of which heroes belong to which civilizations/religions. Some are obvious (like the religious heroes that are unlocked by the religious techs), but others are less so. It makes it very hard to decide on what technologies to beeline when playing new civs if it is unclear where in the tech tree their hero is unlocked.
Here are some places where it would be nice to see a comment on who the hero belongs to.
Civilipedia entries:
Under the description of each hero (i.e. National hero for Amurites or Religious Hero for Fall of the Leaves).
Under the civilization entries (listed as unique units or a separate hero entry if possible).
Under the religion entries (same as civilizations).
Mouse overs would be nice in the technology screen, unit icons, and other appropriate areas.
