I would love to see newspaper obituaries added! I've found my best 'leads' from obituaries - married names for females, location of residences and cemetery location of the deceased!
In addition to the names of the local newspapers, it would be nice to have a cross reference to the state repositories (i.e. University of GA for Georgia newspaper archives and Florida State University for Florida newspaper archives). It's my understanding that a project is underway where each state has a university housing the achives.
