 The first record of this village's name comes from 1270, when it was given as "Isinbach".Other forms of the name that the village has borne over the ages are "Ysenbach" (1332, 1446, 1480 and 1545), "Ysenburg" (1460) and "Eißenbach" (1593).According to researchers Dolch and Greule, the name prefix "Isen—" or "Eisen—" (the latter and current form being the German word for “iron”) refers to the iron-bearing inclusions that crop up in the sandstone deposits near the village.
