- Kastler (*1385 - †?)
- Christian Kastler (*1410 - †1475)
a) Petrus was from Naw (Langenau) - only 6.5 kilometers from Asselfingen. In the town of Thalfingen some miles from Ulm, there is an old abbey. In the abbey church is the stone of his grave in the stone wall still today with an inscription. He lived in the Roman-Catholic times and was an Catholic priest. Ulm and most of the villages which belonged to Ulm took the decision for the reformation. After this, all the inhabitants became Protestants.
b) (Research):Curt Kastler: I have added Petrus as a child to Christian, however he was most likely a cousin to this family.
c) GEDCOM file: Swabian Kastlers.ged
