Hi again - I have finally scanned this Benjamin family tree that a number of my grandfather's cousins put together in the 1990s.
On the very last page is a notation regarding my g-g-grandmother Feiga Yavner Benjamin and her brother David Yavner.
Ancestry doesn't allow PDF attachments on the message boards , but you should be able to view the file here:

Thanks,
