Theoretically (with my admittedly less than cohesive knowledge which is supplemented a good deal by Bleak House), whatever remained of Alice's parents' estate would have been held in trust for Alice at her majority. I think what's going to skew her experience with finding it the most is WHO is the administrator of the estate. Because given Alice's insanity and minority, the administrator would probably have a lot of leeway to do what he wanted with it if he didn't want to hold it so much as use it.

So that might be the first thing to determine and then go from there. I think Alice would need to have someone declare her sane in order to inherit anything more than personal mementos.

...I'm really trying to resist getting in my car to go to the damn law library right now. :D
