Re: Elrond and Elros

In the beginnig there was only Elrond planned, Elros came in later:

And of like fate were those fair offspring of Elf and mortal,
Earendel, and Elwing, and Dior her father, and Elrond her child.

History of ME, vol 4, The Quenta

I can't recall any clear evidence of those two being twins, but from the following quote:

...and he took to wife Elwing the fair, and she bore to him Elrond and Elros, who are called the Half-elven

Silmarillion, chp 24, Of The Voyage of Earendil and War of Wrath

Following the quote, it may be assumed they were twins indeed, for they are not named separately, but together in a manner of speech to imply they were equal and alike in all ways.
