Outside of Aldouin....I can't remember anyone. lol
I played like 100 hours too.
Whereas off the top of my head I remember from The Witcher 2:
Geralt, Triss, Vernon, Iorveth, King Henselt, King Radovid, King Foltest, Saskia, Phillipa Eilheart, Zoltan, Letho and Dandelion.
That's just some. Good storytelling does that.
