I know nothing about Webb's famous or infamous. This cought my eye because my Uncles family finder is pulling up some possible Webb ties.
But-- I do own the Index to Early Tennessee tax list by Sistler, printed 1977
Jesse Webb was on the Tax List Jefferson Co 1800 and 1822.
And there was also a Thomas Webb on it in 1822.
One thing that you might consider also, and again, I know nothing about Jefferson Co. is that it is possible that the county was reformated at some time and that the county lines have changed. Tn Gen Web for Jefferson could probably give you any county boundry changes.
