The Silmarillion also states that Finrod was the first of the Eldar met by Men, but this might be one of those cases where Tolkien had something more specific in mind, in this case maybe "Eldar in Beleriand" rather than "Eldar of the March". However, Men on their way west did have dealings with Dark Elves, so maybe the Sea of Rhûn is indeed one of those places where such dealings happened, but the later text just omitted to mention it.
