Note that the Hess Family Tree (S429) conflicts with the list of children here. It shows George and Amelia with 5 children: Gustavus Friedrich, August G., Walter, Frederick, and William, omitting Louise Borner (b. 1873). It further suggests that William was Amelia's son from a previous relationship, but has no citation for that. William was born the 4th of 6 children though, so it would be difficult for him to have come from a "previous relationship."
