Take a look at the background report on Cageprisoners.com:

[excerpt]

"The report currently is limited to presenting the names of the male detainees. However, it is now [May 2004] believed that there are also female inmates in Guantanamo, at least one of these - whose nationality and age are unknown - has been reported in the press, as an alleged “al-Qaeda member” arrested in Afghanistan and transported to Cuba."

There are news headlines in the Guantanamo category on this site as well.

There is a Wikipedia entry on the Guantanamo Bay detainees with links to other lists of names.
