There are two main versions to the myth of Aphrodite's birth,
one, that she is the daughter of Zeus and Dione: in this any son or
daughter of Zeus (Dionysus, Apollo, Artemis, Athena) would be a
brother or sister of Aphrodite.
In another Aphrodite is the "daughter" of Ouranos (Heaven) born
from his blood as he was castrated by Cronus - this would make her
a sibling of the Titans (Oceanus, Coeus, Crius, Hyperion, Iapetus,
Cronus, Theia, Rheia, Themis, Mnemosyne, Phoebe, and Tethys) the
Elder Cyclops (Brontes, Steropes, and Arges) as well as the
Hecatoncheir (Kottos, Gyes and Briareos) born also from the blood
of Ouranos were the Erinyes, and the Giants, as well as Telchines,
the Phaeacian men and Aetna.
