Footnote is an interesting social network: it contains entries and social linking for dead people.
The concept seems morbid at first thought; however, it does provide a structured place to remember the dead, as well as provide links to others they were connected with.
Areas of the site worth noting are the Pearl Harbor Muster Rolls and the Vietnam Veterans Memorial. There are also a variety of Revolutionary and Civil War lists.
To gain an appreciation of the social aspect of this site, check out the Recent Connections page.
Keep this site in mind for the potential geneological information.
