Actually, "Burnfoot" was his nickname. He fought for the British during the American Revolutionary War. At one point during the war he was caught/captured by the colonists and set on fire by them. His foot was very, badly burned, & he never fully recovered from his burns. He was the British superintendent of the Cherokee & Creek. During the war, he fought in SC. & GA., & possibly in what in now [then Spanish Florida?] Florida.
After the war, he lived briefly in FL., then went to the Caribbean/Bahamas [was awarded large land grants by British government in Bahamas], [possibly Jamaica too] Abaco Island, and died in 1825. I believe his father was a ship builder in England [& his name is in public records]. There is much written on Thomas, but little on his personal genealogy, family, parents, children, siblings, aunts, uncles and relatives. Few public genealogy trees even list him.
If anyone knows whichbrownsociety.orgfamily [DNA] group # his line of Browns/Brownes belong to, I'd appreciate that information.
