Looking for info on Christian Aalborg, his wife Sophia, and their children Abraham, Carl (Charles), and Aaron. Aaron was born in Racine, Wisconsin 1870-1871 according to his obituary.But, I can't find any info on them in Wisconsin. They moved to South Dakota about 1875 and I've found a lot of records from there. They may have been going by their original surname, Jensen, while there. They changed to Aalborg sometime after leaving Denmark and arriving in the U.S. Any help would be greatly appreciated.
