Your great-grandmother Bertha's Hebrew name reads Bella Chaya - they are
both common names...
Your great aunt Sylvia's name is Havtola Zlada...
I am not sure what the first name is/means, but the second can be Zlata...
My great-great-grandmother was Lottie in English, but Zlata in Hebrew....
It can also read Zelda, although I was never aware Zelda was a Hebrew
Don't quote me on these.. I can read Hebrew and can recognize most
Hebrew/Yiddish names, but I am not fluent.. I am sure most Genners can
give you a more precise answer..
