Is it possible, that I could be part Jewish-German?
Added (1). you see I'm very curious about this because I don't know much about jewish heritage or jews in Germany but ive been doing my family tree and it turns out my 6th great grandma was named Rosina Kringerin (1780s) but as I was doing my research ive found out her last name may be jewish as well as her mothers which was strauss, and her grandma's last name was Metzger. Idk tell me what you think about this situation.
