When you think about it as far as we are aware gamzee is the only troll who out lived their dancestor (as in they were alive at the same time but the ancestor died first) so aradia and tav dont count because they werent alive at the same time. (Helmsman may or may not have been alive at the same time as sollux but i doubt it)

The Psiioniic, Condy and likely the Highblood were alive when the Kids started the game. Darkleer is dubious but he could’ve still been alive. All of them died as the Troll Session started, except for Condy, who survived until Collide.
