Today, I called the Federation of Danish actors, but unfortunately they didn't have Karen in their files. Do you know whether she continued being an actress? I also called a revue museum, but they referred me to the Royal Library or the Danish National Archives. I called the Royal Library, but the people that might be able to help were busy. I haven't done more for now.
I also called a few people with the lastname Leisted, but none of them knew about Karen and her family. I left a message on a few answering machines but haven't heard back. I found people with the Leisted middle or lastname on this telephone directory: http://www.degulesider.dkhttp://www.degulesider.dk.
