She was born on Windfall Island, and has lived there her whole life. It is known that at one point, she used to have a boyfriend, but she never speaks of him. When Link speaks to a certain Fishman, he talks about how he and Gillian used to watch the lighthouse together. It may be possible that this is the boyfriend Gillian refuses to talk about.

- ↑ "I wonder how long it's been since the light in Windfall's lighthouse went dark... It was quite a grand sight, I tell you, the way that ray of light shone out like a shaft of gold through the cold darkness. I used to gaze at it with dear Gillian... Anyway, I bet if someone could shoot a powerful spark into the top of that lighthouse, it would light up again! Of course, that's just my intuition talking... Then again, you should never doubt a fish's intuition, small fry!" — Fishman, The Wind Waker.
