Indian Reservation in Virginia?

I knew that the famous Chief Powhatan and his daughter Pocahontas were from (what is now called) Virginia, but I never knew quite where, or if any of their people were still around, much less if there was a sovereign nation inside of my state. Apparently there is such a place, The Pamunkey Reservation, and it's west of Richmond near central King William County, and this historically important people still dwell there.
