'for they were born before the world and are older than its oldest, and are not of it,'

How do we know that Ungoliant was older than the world? She only ever appeared after it was already created, after all.

Goldberry was surely a Maia. I wouldn't have thought there was much case for a suggestion to the contrary. She did not have children.

Most, if not all, of these spirits of the land that are mentioned would be Maiar. How many Maiar there are we don't know, but the forms they took and the strengths they all possessed varied immensely. There are a few anomalies, but don't include obviouslu un-anomalical ones like Goldberry in it.
