The triplets I had in my game are called Artemis, Alexis and Asterion.
They are the grand children of Alexander Goth and Stella Terrano (from Sims 2 University, I recreated her for my game).
Alexis is an alien and she is named after Alexander.
Asterion is a spellcaster and his name means "star". He was named after Stella. Asterion also was the name of a king in Greek mythology.
Artemis is also a spellcaster and she is named after the goddes of hunt in Greek mythology.
I spend a lot of time choosing the right names for my sims and I love it. :) The names of the descendents of the Goth family are mainly inspired by the Roman or Greek mythology in my game.
