Heiligenkreuz i. Lafnitztal

Poppendorf has always been a branch of the parish of Heiligenkreuz im Lafnitztal.

Rába-Füzes (Hungary) belonged ecclesiastically to the parish of Heiligenkreuz i. L. Since the establishment of the diocese of Eisenstadt, Rába-Füzes has also belonged ecclesiastically to Hungary.

The registers of Oberradling, Inzenhof, Jakobshof, Tschanigraben and Fuchsgraben are matriculated in the books of the parish of Heiligenkreuz i. L.. The parish of Oberradling (Hungary) was established in 1789. The following parishes belonged to this parish: Oberradling, Inzenhof, Jakobshof, Tschanigraben and Fuchsgraben. In 1921, this parish of St Emmerich was divided by the demarcation. Inzenhof, Tschanigraben and Fuchsgraben became part of Austria, but continued to receive pastoral care from Oberradling. This became impossible in 1948 when the barbed wire fence was erected. Inzenhof, Tschanigraben and Fuchsgraben were now looked after from Großmürbisch. Since the establishment of the diocese of Eisenstadt, the parishes of Inzenhof and Tschanigraben and the Fuchsgraben hamlet belonging to Inzenhof have also been ecclesiastically separated from the parish of Oberradling and now belong to the parish administration of Großmürbisch.
