Nessa and Tulkas are indeed the first meaning, and I can tell you that they were supposed to be the
only meaning. The original second line was 'Crowned with gold and named there-for', referencing Tulkas' Valarin name - but I changed it.
No comment either way on whether I'm being tricksy (
), but I'm afraid Esgalduin-Sirion is not an answer I'd thought of.
