No, Artemis was an Olympian goddess. The Olympians are the main Greek gods, so that would make Artemis a major (not minor) goddess.
Artemis is a whole goddess.
Artemis had sworn to be a maiden her whole life, so even if somebody wanted to marry her, she'd refuse and probably get very angry. No god requested to marry Artemis, though certainly many mortals would.
Artemis.
Hmmmm.... Artemis was the goddess of hunting, wilderness and animals, however Poseidon was the god of fish and the sea. I would say probably Poseidon because when fisherman or sailors would set out on a journey they would give offerings to Poseidon, not Artemis.
Artemis was a goddess herself. No other god had control over her.
I'm not sure if there is a god of childbirth but the goddess of childbirth is Artemis.
Artemis was the Greek goddess of the moon.
Artemis was goddess of the hunt, and anyone hunting would have made an offering to her before beginning an expedition.
Artemis weapon was a bow and arrows.
Hunting
Artemis would know that there is nothing in Greek myth that a Greek god controlled that a Greek goddess did not have had a domain over as well.
