Did not take a lot of research to figure out that the correct name is Buckfolde. The "Gent" came from a tree that everyone seems to be copying that has the father as "Sir William Buckfolde, Gentleman" That got shortened to Gent and finally in copying lots of times, as people do....it became his last name.
However, even that initial tree has NO SOURCES to prove any of the data or spelling, as far as I can tell, this is a person made up as Baron of Kent, Sir William Buckfolde, Gentleman
