If you are on Facebook, join this group to ask for assistance researching Argentinian Jewish history.

https://www.facebook.com/groups/Gen.Judia.AR/

The discussions tend to be in Spanish, but the translate button under each post does a decent job and you can write to the group in English.

The Facebook group belongs to: Agrupación de Genealogía Judeo-Argentina
