 It can no longer be ascertained when today’s village of Offenbach was founded.Places with names ending in "—bach" ("brook" in German) were founded over rather a long time, and it therefore makes little sense to speculate about the village’s exact time of founding.It is known for certain, however, that the village already existed in 1150 (according to another source, however, Offenbach is mentioned in documents from 1128).
