Re: Information on Jewish community in Landskrona, Swedish #scandinavia
There is quite a bit of info in Swedish on the local Jewish communities.
The wiki article www.wiki.rotter.se/index.php.Judar has a lot of material and links.
Sveriges Släktforskarförbund. also has an English page where you can make contact with relevant groups.
I have not done a detailed search but it appears a lot of data has been collected on your subject.
good luck, lycka till
