I'm curious although a bit confused as to what heroes we're supposed to be descended from.  Link specifically or any Sages or even Ralph for example?

Mostly link and Zelda. It's not a direct descendance. It's essentially that through the magic of times wimey stuff you somehow ended up with some Dna from any link or Zelda from any timeline. It's not really that important becuase it's confusing. It really just explains why you can be a different race from Hylian and still be descended.
