For a true historian's take on the Seminole Wars, I recommend:

  • The Seminole Wars by Mary Lou and John Missall
  • History of the Second Seminole War by John Mahon
  • In Bitterness and in Tears: Jackson's Destruction of the Creeks and Seminoles by Sean Michael O'Brien
  • Coacoochee's Bones by Susan Miller
  • Hunted Like a Wolf by Milton Meltzer

I also love The Seminoles of Florida coloring book by Art Maynor. 

The Ah-Tah-Thi-Ki Museum in Clewiston, Florida, is a terrific resource.  The museum at the Dade Battlefield (northeast of Brooksville, FL) is also top-notch.
