As far as my line goes everyone hasspelled it HUSTED as far back as the late 1500's. The only 2 that actually spelled it Huested were the first 2 generations, perhaps you should back off a bit. Most of the names recorded in Census records were written by the people taking the report and not the family. So most of the spellings you will find are not correct. If you want to spell it Hustead so be it.
