Florida was under Spanish rule from the 16th Century until 1763. In 1763 Spain ceded Florida to Great Britain at the close of the Seven Years War. France lost all territory and Spain controlled Louisiana.
Great Britain divided Florida into two Colonies, East and West Florida. Daniel Boone journeyed to West Florida before his forays into Kentucky but Rebecca refused to consider the subtropical and distant Floridas.
At the time of the Revolution there were 15 British Colonies. Since East and West Florida was sparsely populated and garrisoned by troops they remained loyal to the Crown and became a haven for Tories.
Spain, allied with the United States and France, invaded Florida from Louisiana in 1781. As a result Spain regained the Floridas.
Spain held Florida until 1818 when it was purchased by the US after Andrew Jackson's Invasion in the First Seminole War.
The population of Florida would be Spanish, French, English and African in settled areas like St. Augustine and Pensacola. In the interior were Muskogees and Africans who became known as the Seminole.
A large number of English Carolina Type G Trade Guns have been found in Florida. Spain did not have a strong gun trade with the Indians.
So most guns in Florida would be French or English types, mainly English. I'm sure you would find some Spanish guns too along with a few American longrifles.
