There is only one global list of people that anyone can view and edit. There should be user accounts, each with its own set of people.
When you create a relationship, the relationship type, person, and related person all have to already exist. You should be able to add a type and/or person from the new/edit relationship forms.
Also, probably you should just be able to edit relationships directly from the edit person page, rather than having to go to the list relationships page.
When you show a person, it shows both forward and backward relationships, e.g. you see both parents and children. You can only add/edit forward relationships, though; you should also be able to add/edit backward relationships, e.g. add a child to a parent, rather than having to navigate to the child and add a parent.
UI styling would be nice... Also AJAX.
