Yes. I will help. We are slowly building the categories for Denmark, but probably would not get to this area on our own because the Project pretty much focuses on the area that was Denmark after Sweden and Denmark split and the area you are working with is in the area that was ceded to Sweden in 1658. The period before 1658 is a time when Sweden and Denmark were under the rule of the same monarch which is why Denmark gets associated with these areas in this time period. Anyway, this geographic area is under the Sweden Project, and that is where you will find the applicable categories.
I see you created a Category: Skånelandene (-1658), Danmark . Skånelandene is an area on the Scandinavian peninsula, including the Swedish provinces of Blekinge, Halland and Scania. The Danish island of Bornholm is sometimes also included. Since it was never an official geographic name, I probably would not create a category with that name.
I would probably use Category:Skåne_landskap for the province of Scania; Category: Blekinge landskap for the province of Blekinge; and Category: Hallands landskap for the province of Halland. The Sweden Project created these categories and notes that they go back much further than the 1630's when the counties were created, so they cover the time period you are interested in.
You could put all 3 on your free space page if you think the family members may be in more than one. If you can narrow the focus to only one of them, then use that one alone. Then as you create profiles for specific people and learn where they were born and died, you can use the appropriate category or even more specific location categories from the Swedish hierarchy of categories.
Stångby is in Skåne county and was in Skåne_landskap so that might be what you want to use on your free space page.
