Did Legolas have any brothers or sisters?

I was assuming we were considering the final stages of the Third Age, wherein the elves were beginning to dwindle and shrink from sight.

Then wouldn't elves be trying to have a lot of children, to try and increase their number?

I personlly think that Legolas did have brothers and sisters, atleast 1, just so that if anything happened to one kid Thranduil would still have another heir. I mean, ya he's immortal, but elves still die, in wars and such, I think he would want to be 100% sure that there was an heir sitting at home ready to take his place if he perished. Only having one kid doesn't garantee that.

Though it's possible that, since Legolas' mother is never mentioned, she may have died somehow, right after Legolas was born, and never had the chance to have other children, and a broken hearted Thranduil never re-married.

Practically anything is possible.
