I'll give you 48 though I've never seen the weapons do it but maybe its been awhile since I've played V.

EDIT: Scratch that, I'm having a brain drain and forgot about items like the Gaia Hammer in V so yeah. Though I did change it somewhat...

As for 39, Galuf is Krile's grandfather, while I guess one can argue their relationship is parent to child, I'm not counting it.

58. VI is the only game in the series that has a cursed item that can have the curse removed.

59. There are a total of 3 Memento Rings in the game.

60. Although fixed by the GBA release, their is a bug that makes the Evade stat useless, instead the game takes the evade stat from from your M.Evade which is why the White Cape Relic is so freaking awesome.

61. If you watch the CG ending to VI from FF anthology, when you watch Shadow fight the ghosts on the train, their is a quick flash, if you slow it down, its an image of Relm from one of the Amano designs.
