I'm glad the posting gave you another lead.
I do check this board (but rarely) but it is bookmarked, so I wanted to see if you had seen the post. My email address is deliberately incorrect. I get far too much spam.
Make sure you post on the active board I suggested. Many more people will see it and a good percentage of those might be from Nebraska.
If your friend has a birthdate, the Swedish records are absolutely fantastic. They are among the best in the world for genealogical detail, and all the parish records are microfilmed. The records were kept in the parish. The names changed each generation because of patronymic naming customs but that isn't a problem.
U.S. records aren't nearly as easy to use. Few, if any, countries have records which can match Swedish genealogical records. Your friend is very fortunate that ancestors were Swedish.
The Swenson Swedish Immigration Research Center has solved problems for many of us, but their records aren't online.http://www.augustana.edu/administration/SWENSON/
For example, they have records for these churches in Nebraska.http://www.augustana.edu/administration/SWENSON/SwedishAmeri...
They have a lot of Swedish-American newspapers too, which are great for more detailed obituaries than often found in English language papers. A lot are for Nebraska.http://www.augustana.edu/administration/SWENSON/Newspapers/N...
