Who were the siblings of goddess Venus?

In one she was born from the castrated genitals of Uranus which fell into the sea. In this story her "siblings" were perhaps the Erinyes, the Gigantes and the Melian nymphs who were born from the blood of the same castration.

In another genealogy she was the daughter of Zeus and Dione. Sometimes (but extremely rarely) the god Dionysus was given the same parents and made her full brother.

As a daughter of Zeus most of the other Olympian gods and numerous heroes would have been her half-siblings.

In the story of the Rape of Persephone, Aphrodite is described at play with her half-sisters Persephone, Athena and Artemis.
