What does this surname mean? Because the Cause of Death is listed as a Still-born, I presume that Ritter S/B. OF. means stillborn of Ritter, which means that I should index the surname as Ritter, NOT Ritter S/B. OF. Is that correct? Please correct me if I am mistaken.

I interpret that to mean a stillborn child, unnamed, of Fredrich Ritter and wife Helga.
