Thank you Judy for all this information. My great-grandfather was Kristian Hansson, who came to the United States, which is why you didn't find him in the death index. I am still trying to create more of a narrative around his family that remained in Sweden, and perhaps the only good way to do that is to make contact with living relatives. How does one go about learning of Kristian's nephews and nieces that lived and died in Sweden, and from there find out about any living relatives? I have already found many of them with ancestry's birth index 1880-1920, but this doesn't allow for finding information on people born after 1920 or who are still alive.
Thank you
