At the Minnesota Historical Society, on can view all death certificates, by year and county. It sure would be nice to know if his parents are listed. It should also tell who provided the information, this may lead to a child of theirs. The local newspaper can provide the death notice their should also be family listed there. I currently live in Texas and only infrequently return to Minnesota to gather more genealogy information. Just last summer I was in Minnesota and gathered some information on this family. If we can link this family it will add to the overall family information. It is my belief that this family came from Minnesota.
