My first suggestion would be to go to the Given Names Data Base on
Jewishgen, select Foreign to European and put in Klara and Bertha.
My mother was >from Warsaw, but her middle name was Bertha which she
hated. She was named after her paternal grandmother and whose Yiddish
name was Niche Breindel (and that was also my mother's Yiddish name).
She had a Hebrew equivalent for the Niche (Menucha), but none as far as
I know for the Breindl.
I hope this helps
