I don’t think that has ever been mentioned, but what are the original (pre selling to corps) names for the bodies in the Stanton System? I assume Toshi Aaron named all of them and we know that at the very least the planets and the moons of Hurston were renamed after being sold.

Planets aren’t usually given names until they are recognized by the Senate. The naming of moons is much more flexible, and tends to happen over time via nickname. Discoverers of a system can request naming rights for moons but this hasn’t always been granted.
