Some of the sections of that website are more filled out than others. This entry comments directly on the whole "brother's war" aspect of the family's participation in the Civil War. The entry is on another set of cousins, a captain and his private brother from the Isaacs branch, one of which died in the Atlanta campaign. That makes at least four Thorn descendants present at that campaign, counting the Wirt County Thorne, the Thorn of the 150th New York, and the two Thorn Isaac brothers.
