My husband insisted I was making up the name of an island. I am not, but it was the colonial name, apparently; I'm sure he knows it by its Africanization policy name, Bioko.
For those of you using a reader to see this, I will spare you the agony of having to google the name Bioko. The name he accused me of inventing (which, actually, is a reasonable accusation): Fernando Poo.
Wikipedia says that it was used in the Illuminatus triology. I only ever read a tiny bit of The Eye in the Pyramid, but perhaps that's where I learned of it. If I ever become a drag king, I am changing my name to Fernando Poo.
