Well I guess it will be all the oldest elves, which means the kings and queens and their children, a few more elves who are important, and some charcters for the frame.
Just a couple of examples: it's Finwë, both of his wives, his sons, and their children, among whom some have children of their own - for example Celebrimbor, who was born in Valinor and joined his father in the journey to M-e.
