When writing the history of a character, particularly a Greek character where many scholars and poets and writers have said so many different and conflicting things, how are people deciding which lineage to choose? Different sources suggest different siblings, parents, children, etc, so what if what you decide conflicts with another writer's interpretation of the character's supposed sibling?

For example:

God A's profile suggests God B is his/her sibling, but each cite different sources and scholars, and so God B's information suggests they are indeed, not related.

Sorry. Late. Confused. Trying to touch up an application for a Greek. Too complicated!
