 In another document, from 1363, they are called the “two Jeckenbachs”.Particular names for Unterjeckenbach then also crop up in the historical records, such as "Sienjeckenbach" (1448, after neighbouring Sien) and "Frygechenbach" (1448).In old writings, and even today in the local speech, the “two Jeckenbachs” are also called "Geckenbach".
