I am trying to find the location of an old farm, "Hallnäs Nr 5," on a modern day map. I have used the historic maps on Lantmäteriet without success so far. Lantmäteriet’s modern map of Hallnäs shows eleven homes whose property designation begins with the number five. How does one go about finding the "parent property" Nr 5 when there are so many subdivisions? I would appreciate any tips or suggestions you may have on the process and what steps I can take next. Thank you!
