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.
So you could say that because Link took on the form of a Gerudo, Zora, Goron, or Deku Shrub there is a child who budded off of a pseudo-timeline where the mask wasn't removed when the various Terminan timelines merged together at the end of the game?
