I hope the formatting of this message isn't too messy....
Is Bischofsburg Ostpreußen - which is listed in the JewishGen Town Finder - the same place as that in the screenshot "Bischofsburg Koenigsberg"?
The town in the town finder is also listed as "Biskupiec, Poland".
However, does this link suggest that page suggest that "Bischofsburg Koenigsberg" is a region? https://de.wikipedia.org/wiki/Kreis_R%C3%B6%C3%9Fel
(Please excuse the warping of the special characters in the link!)
Many thanks for your help.
