What connection between Goldberry and Ulmo?

However let us not forget that beings of own free will don't come out of nowhere in M-E, and ultimately, if Goldberry has free will or her own fëa (well, maybe she has not?), then in any case, she would have to be given the life by Eru - like the Dwarves, at maximum. Then, speaking very vulgarly, her body would be marred, but her spirit would be good and capable of remaining even across the destruction of Morgoth's Ring.

However, one more thing about the nature of water. Even assuming that Goldberry is in some way coming out of water, her profile would still be quite fine! Why? Because water, out of all materials of Arda, was closest to the Music, and it is overall presented as something positive (Melkor wished to destroy it; Black Riders could not cross the water !!! etc.).

So doesn't that mean that Goldberry could not be marred, because water could not be marred?
