Here's another description of giant size people in the past in Florida...
The Spanish Conquistador and explorer Pánfilo de Nárvaez faced a disastrous failed invasion of Northern Florida after losing most of his men to native attacks and disease, lack of adequate supplies, and being abandoned by the very ships that had brought them there, and in the wake of this he himself would go on to disappear after departing for Cuba on a makeshift raft.
One survivor of the whole perilous ordeal was a junior officer named Alvar Nuñez Cabeza de Vaca, who along with a ragtag group of others decided to make a beeline for safety in Mexico, which they mistakenly believed to be much closer to where they were than it actually was.
They built a raft and departed on their ill-conceived flight, and De Vaca would go on to survive the ordeal and make his way all the way to Texas, before finally returning to Spain and eventually writing a bestselling account of his adventures. Buried in this journal is a very strange and rather harrowing account in which this motley group apparently came across a group of mysterious and very aggressive giants while crossing a lake in Florida.
De Vaca would claim in his journal:
"When we attempted to cross the large lake, we came under heavy attack from many giant Indians concealed behind trees. Some of our men were wounded in this conflict for which the good armor they wore did not avail. The Indians we had so far seen are all archers. They go naked, are large of body, and appear at a distance like giants. They are of admirable proportions, very spare and of great activity and strength. The bows they use are as thick as the arm, of eleven or twelve palms in length, which they discharge at two hundred paces with so great precision that they miss nothing."
