Perhaps you would be interested in lookups on the 1970 and 1980 Swedish Census CDs and the CD "Swedish Death Index 1947-2006". I have those cds but specific information is needed.
Remember that if you advertise on the Sweden board, you have a better chance of finding those living relatives or a Swede able to help you find them. I told you about that last time, I think, but if not, it is a board on Genforum.
I found living relatives in the U.S. by combining a number of sources, including information found in the Swenson Swedish Immigration Research Center. The Swenson Center has a website but their extensive collection of records is NOT online.
