I'd imagine it wouldn't be too dissimilar from noble families in our own history who have taken/received family crests for whatever reason.
probably related to what they've contributed to their societies, rather than some "prophecy."
Yes, it's called discovering the Phantom Zone. Hence the \S/ as the family crest which I've read to mean "The serpent of deception in the prism of truth." Or something to that effect. Tales of the dead earth annuals back in the 90's. The Superboy annual set on another planet with the decendants of Superman's family being the monarchs.
