Joe Fibel made the suggestion - when trying to reach someone overseas or locally
(the U.S is overseas for me!) - of contacting local Jewish Genealogical Societies,
after identifying them through the International Association of Jewish Genealogical
Societies site www.iajgs.org
Irrespective of Joe's valuable suggestion, and just to avoid duplication of efforts
in this particular case, please allow me to say that the contact with Albertina
PITERBARG is already solved, and the contact information has been shared privately.
