Hi,
WELCOME to Rootschat from me as well.
I agree with Tony (TonePad), can see the second word and the first letters do not match, so unlikely to be "Barth".
You posted "Bronislawa Barth. We know this much already"
You have not proven with a reference as to why you know this much already.
Any chance of proving that of what you are convinced?
Cheers
Ray
