Calypso was a goddess nymph. Her father was the Titan Atlas. His other offspring were the Pleiades, the Hyades, Hyas, Maira, Dione and the Hesperides, so I suppose they can all be considered Calypso's siblings.
The story of Calypso IS as myth, see the related link I will make below for the details.
Calypso wasn't on any side. She was trapped on her island. Odysseus sailed onto her island and stayed with her for many years. He fought in the Trojan war, but Calypso never was on a side.
