On the top of my head, I can also name some more, like the Muses and Ganymede, but, are there other people who lived on Mount Olympus?
When you think of Olympus, your mind usually goes straight to the big twelve: Zeus, Hera, Poseidon, Demeter, Athena, Apollo, Artemis, Ares, Aphrodite, Hephaestus, Hermes, and either Hestia or Dionysus.
However there are Minor residents as well. Ganymede and the Horae are indeed found on Mount Olympus, as well as many others (see here for a list). They aren't technically counted as "Olympians" but they reside on Mount Olympus.
