Hi Antonia,
unfortunately i cannot help you in your research for PAPPE.
But maybe i have a hint for your question in locating Aldenberg/Oldenberg. First of all make sure if you are not looking for OLDENBURG (Old.) west of Bremen and about 140 km north of M�nster or for OLDENBURG (Holstein) near the city of L�beck.
ALTENBERGE is a small town approx. 20 km north of M�nster.
