History of Koenigsberg/ Kalinengrad.
How about a Russian Yekke?
Is that so important ? Or why is it so important for you?
My mother-in-law was from Koenigsberg. I related to her as a Jekke.
She grew up with German culture and language.Was German culture more respectable for all Jews living in Germany at the time?
Did they hide any East European family history from "real" Jekkes?
Where were her parents from?Her maiden name was Kovner.
Other relatives on her mother's side were from Russia.
Kovner Name Meaning
Jewish (eastern Ashkenazic): habitational name for someone from Kaunas in Lithuania, from its Yiddish name, kovne (Kovno in Russian).
