Annemehr:
I'm not sure this is true. I think what LV learned from Bertha was:

~Crouch Jr. and the Lestranges tried to find LV after he'd disappeared
and were sent to Azkaban for it (this is common knowledge).

~Crouch Jr. was being held prisoner by his father and thus available
to LV as the Azkaban prisoners (also faithful, presumably) were not.

LV already knew Crouch Jr. was a DE, of course, and the first item of
information is what told him that Jr. was faithful.  Thus, Bertha need
not know anything more than "she should."
