Sometimes Clymene is her daughter

"Falling desperately in love with Helen, the most beautiful woman in Greece, he carried her off, along with much wealth, and also Aethra and Clymene, being Menelaus' relatives, attended on Helen.

"Meanwhile the Athenians welcomed Menestheus along with Aethra, the daughter of Pittheus, and her daughter Clymene. Demophoon and Acamas, however, remained outside the city" -Dictys Cretensis, Trojan War Chronicle

related to and important to Menelaus "with Aethra the relative of Menelaus from Pelops and Clytemnestra from the lineage of Europa"

"together with Aethra from the lineage of Pelops and Clytemnestra from the lineage of Europa" "King Menelaus the theft of Helene by Paris, and that he took along with her Aethra his and Clytemnestra’s relative. Menelaus on hearing this was flabbergasted. He was very sorry about Aethra, for she was esteemed by him as being very proper" -Malalas, Chronography 

worked with athena and built a temple "In obedience forsooth to a dream from Athena, Aethra crossed over into the island with libations for Sphaerus. After she had crossed, Poseidon is said to have had intercourse with her here. So for this reason Aethra set up here a temple of Athena Apaturia, and changed the name from Sphaeria to Sacred Island. She also established a custom for the Troezenian maidens of dedicating their girdles before wedlock to Athena Apaturia" -Pausanias, Description of Greece

Now there is another thing that falls under "Gee, that's interesting" funny. Theseus is descended from Pelops through his maternal grandfather Pittheus, meaning that Theseus' mother and Helen's slave Aethra is the first cousin of Agamemnon and Menelaus, their father Atreus having been a son of Pelops just like Pittheus.

When Aegeus visited the oracle to know why he can’t have children, it gave a cryptic message that basically meant that he is not supposed to impregnate a woman until he is in Athens.

When he goes to Troezen to visit his friend Pittheus, he immediately understands the oracles message and so he gets Aegeus drunk and has him sleep with his daughter Aethra in Troezen (for whatever reason?).

So if you notice, Aegeus got Aethra pregnant OUTSIDE of Athens meaning that Theseus birth was in defiance of the Oracle’s command. This was actually brought up by Plutarch himself to explain all the bad things that happened to Theseus and everyone else around him because his existence was against the will of the gods.

Pittheus: I need you to sleep with my drunk friend Aegeus

Aethra: .... Ok then

Athena: I need you to meet and sleep with Poseidon

Atreus and Thyestes

Troezen and Pittheus are like the good versions of Atreus and Thyestes, bet if Hippodamia asked them to kill Chrysippus they’d be like “no mom wtf”

Not "Ha ha" funny, but "Gee, that's interesting" funny.

Theseus' maternal grandfather Pittheus was the son of Pelops, who was also the father of Atreus, Menelaus' father.
