FFIX possible Sequel to FFII?

[Solleks]

I decided to play through FFIX again, my favorite final fantasy ever. Well, I got to the part where you first meet Ramuh, and you have to give him the peices to the story...But in it, the part talking about how the adventurers had to go to the mountains, but Joseph was killed by a traitor,and Joseph's friend had to tell his daughter about the tragic news.

Well, I just remembered a long time ago back in FFII that you grouped with someone named Joseph, having to go to the mountains to get an item, (Forgot what it was, been soooo long ago.) but he was killed there by a traitor, so can this possibly be a sequel, taking place a long long time in the future?
