Maglor and Daeron

[Finrod Felagund]

Ok in the Silmarillion it says that after Maglor threw his Silmaril into the sea he wandered the shores singing and never came back among the elves. Where'd he end up?

Daeron of Doriath, after Luthien's departure, went over the Ered Luin and made music for many ages, so what happened to him?

Does anyone know?
