Wolf/Eisig Beer Lasar Deutsch - Source of deep Deutsch ancestry

According to Geni I'm a descendant. Why the question? Is there a problem with the data?

Hello Matias Bauer, I seem to be also a descendant (that's what geni suggests, the ancestor I had found is Maria Winter nee Deutsch Maria Winter), and I also wonder with great interest: There is a line going back to Jakob Elias Aschkenasi (b. ~1318; d. ~1388), there is a lot of names, and no source. I am mostly interested to learn about my family: Who were they - they must have been, I assume, a rabbinic family when the ancestry is documented so far back. Where did they live? Almost no older name has any information, although the names usually suggest that they might have lived in German areas. Very curious to learn more. Thanks for any information.

Best regards,
Katarina Holländer
