I wonder if it is indeed not notable that the two grey-haired Elves we see (aside from Gwindor, whose physical appearance was caused by torment and labour under Morgoth) were both of the Teleri. They would certainly have seen more than their share of grief and general stress, much of it due to the Noldor.
