Researching 19th Century Prussia

Is anyone else researching the following families?

    FEIBUSCH Nackel or Naklo Nad Noticea
    JACOBSOHN Santomischel or Zanimysl
    JACOBSOHN Schweidnitz, Breslau

For Schweidnitz, I have a photograph that I cannot identify done by R. Kircher in his studio on 6 Kirchstrasse.

A greatgrandmother listed Santomischel as her birthplace and Breslau as where she visited her cousin (unnamed) when returning from Europe.

I have Temple birth and marriage records for the FEIBUSCH family.

Also researching BLUMENFELD, TOTSCHEK, MEYER, MAGNUS, KREBS, and KALLMAN.
