I mean, those who have a direct role, not merely being an ancestor of someone who did
Melian: It was from her that Luthien got the magic abilities she used to help obtain the silmaril
Luthien: very important, he powers allowed Beren to get the silmaril, that would be crucial later.
Dior: His heroic refusal to surrender the silmaril. Have he given it to the sons of Feanor the silmaril would have never got to Earendil
Elwing: fleeing Doriath with the silmaril, casting herself in the sea which resulted on her being turned to a bird by Ulmo and she would find the Vingilot.
Turgon: built Gondolin, without it is hard to say if Idril would have survived long enough to meet Tuor and give birth to Earendil
Idril: another important one, not just being Earendil's mother. She saved his life when Maeglin tried to kill him. She was the one that asked for the tunnel to be built to escape Gondolin.
Tuor: Earendil's father, also played a crucial role in getting Earendil to safety in the heavens.
Earendil: do I need to say anything?
Finrod, without him Beren would have never made it alive to Angband.
Barahir: His heroic defense of Finrod's retreat would earn him Finrod's oath to help him and his descendants, which was why he helped Beren.
Hurin and Huor: again their heroic sacrifice allowed Turgon to return to Gondolin. Hour's prophecy may have been part of the reason why Turgon agreed with Idril marrying Tuor.
Emeldir: she guided the women of Dorthonion to the relative safety of Dor-Lomin. Without her Rian would probably not have survived.
Ulmo: the architect of the whole affair. He pushed Finrod and Turgon to build Nargothrond and Gondolin, which will keep important actors alive long enough to fulfill their role. He guided Tuor into Gondolin. Protected the refugees from Gondolin with his power over the Sirion river. Turned Elwing into a bird, not only saving her life but allowing her to find the Vingilot, with the silmaril.
