It's Helen Vaughan from Arthur Machen's The Great God Pan.

(I have no merits from a knowledge standpoint tho, I never knew about the book or even the author. I just connected the dots from the goat assets and hint at Lovecraft's inspiring author.)

I believe the reason why evil actionas are linked to this character despite the fact Pan wasn't strictly evil is because of the religious influence of turning anything looking like a goat-person into (an aspect of) the Devil.
