That is a pretty ambitious list! I don't know about all of those, but if memory serves me correctly, there has been research into the 1926 and the 1928 hurricanes as possible Category 5 hurricanes at landfall. I did not see them on your list. That said...Nothing substantial enough to call them Category 5 Hurricanes has been presented at this time. As far as more recent storms, I would dismiss Lenny and Dennis from the list for sure. And in the Recon era, I would also dismiss Georges from the list. All of these hurricanes were very severe none the less. I image that history will remain unchanged for all of these storms.
