I had not heard of a large migration of Hills to FL, but do have Dr. John Ward Hill, son of Stephen Hill, who died in St. Petersburg, FL in 1916. I am descended from Hills who came from MD to Newberry Co. SC and then to Warren County KY and on to IL. What do you have on your Thomas Hill? My 3rd gr.grandfather was Thomas, son of Henry and Alice Ridgely Hill. Pat Hill Martina
