Cronus swallowed each of Zeus’ brothers and sisters. Zeus’ father, Cronus, swallowed his children at birth because he feared that they would take over his spot on the throne one day. The events surrounding their birth were a crucial part of the Succession Myth.
This generation of gods did not become the principal deities of the Greek Pantheon by fate.
To understand who the brothers and sisters of Zeus are, you have to know about the birth of the Olympians.
