Familie von Käser (zum Stein)

[MatthieudeP]

Hello everyone,

Please find attached some data about family von Käser (later zum Stein) in Bayern (XVIII-XIXth century).

They received a nobility recognition & Freiherr title in 1816 and totally changed arms in 1832.

I have two questions about this family : 

1) I did not succeed to find Freiherr Johann Nepomuk von Käser's (Arnstorf 1747 - München 1827) parents ; any ideas about a path to follow?

2) It is very strange a family suddently totlay changes its coat of arms ; any information about this or reason that could motivate it?



Thanks a lot, 

Matthieu
