 The like-sounding mention from 1135 is a forgery from the 13th century.Other forms of the name that appeared in the Middle Ages are "Ophimbach" (1215), "Ovphenbach" (1255), "Uffinbach" (1259) and "Offembach" (1343).Toponym researchers assume that today’s "Ortsteil" of Hundheim in the municipality of Offenbach-Hundheim was originally called "Glana" or "Glene", and perhaps also "Neuenglan", a name that would have distinguished it from Altenglan ("alt" and "neu" are German for "old" and "new" respectively).
