I think one end of this has to be Gil-Galad/Elrond - Elendil - Miriel. There's no other avenues to Numenor apart from Sauron, and like the thread says, avoid.
Hmm... wait, I know someone who was close to Elrond:
Miriel > Feanor > Maglor > Elrond > Elendil > Miriel.
(Those are not 'greater than' signs. I would never place Feanor above Maglor.)
