Did Artemis have an aunt

Asteria, who turned into the island Delos (where Apollo was born) - is the sister of Leto, the mother of Artemis and Apollo.

Rarer myths say that Artemis is the daughter of Demeter, making her aunts both Hera and Hestia.

In any case, from Zeus her father Demeter, Hera, and Hestia are her aunts.
