1. ELROHIR - The rider is but half what he is named; he must go south with the company.
2. LALAITH - Twice following, so i'th'name of laughter is the fiery maid transformed.
3. L Sister to one of our own, she comes from the shore: send her back.

Correct! But she's not just following: she's twice [a note to] follow, so. ^_~ Her original name was Urwen, which means 'fiery maiden'.

There aren't that many sisters in Tolkien's books. Luthien isn't one.

Lalwen/Lalwende and Lothiriel are. And Lalaith.

I feel that the answer needs to be the name of a sister of a Downer's name.

But perhaps it runs backwards, and ends with L. None of the sisters beginning with L seems to fit.

None of those names, but you're precisely right in both whose sister she is (though you could be even more precise), and that she ends with L (and therefore runs backwards).
