Lúthien and Melian

I know Elwë died as a result of greed between him and the Dwarves, but I am not sure of the rest of the 'family'.

Can anyone tell me what happened to Melian after the Ruin of Doraith, and what happended to Lúthien after the War of Wrath.

Did they both sail to Aman? and if Lúthien did, did Beren go aswell?

Curiousity, it seems has got the better on me.....
