According to Rosa and Volker Kohlheim, Familiennamen, Mannheim 2000, there are a few more options:
1. place-names outside Bavaria (Grimma, Saxony; Grimme, Saxony-Anhalt or Brandenburg; Grimmen, Mecklenburg-Vorpommern or East Prussia; this explains the wide distribution of the surname)
2. surname that goes back to a short form of personal names containing the element GRIM, mask, helmet (later confused with "grim") (Seibicke's HDV even lists GRIM as a first name)
