A pseudonymous amateur researcher claim to have documented 106 tornadoes for the 19/02/1884 outbreak (compared to the 60 recorded by Finley) with 75 significant (compared to Grazulis' 37). They've put them in a
Google book which can be previewed for free. It seems they have used newspaper reports as their sources.
Must say, not sure about the tracks that are in rather different directions to the others.
Two years ago I found a report in the obscure
American Meteorological Journal a report, though a not very detailed one, of a tornado that passed north of Stateburg (spelt 'Stateburgh' by the author) South Carolina, a locality west of where Shaw AFB now is. Finley's map isn't precise enough, but if Grazulis knew of it he didn't consider it significant, it isn't on the map on Shawn's (locomusic01) article, and it doesn't appear to be on the above person's map either.
