This search example involves the death records of my great-grandfather Andrew Otterberg and two of his brothers. The death record for Andrew was quite easy to obtain. Family records showed his death date was April 17, 1938 in North Dakota. By 1938, North Dakota was maintaining death records at the state level. So, I searched the North Dakota Death Index and ordered this certificate:
My mother had Andrew's obituary. It mentioned that he had a brother Peter living in Helena, Montana. So, assuming Peter continued to live in Montana, I searched for him FamilySearch.org. There was only one Peter Otterberg in Montana. He died in 1941. Other entries at FamilySearch.org showed that his wife was Anna, which matched other family records I had. Starting in 1907, Montana kept death records at the state level. Here is the death certificate I ordered from Montana:
While researching the family, a cousin showed me a baptismal record that listed Olof Otterberg as a sponsor. No one knew who he was. To find out took some searching. I found an Oluf Otterberg in the 1900 U.S. Census for Moody County, South Dakota and in 1910 for an Ole Otterberg in the same location. Andrew Otterberg also lived in Moody County at those times. So, it is possible that Ole/Oluf in the censuses was the Olof Otterberg in the baptismal record. I searched FamilySearch.org for Olof Otterberg with a death location of South Dakota. There was only one entry for an Ole Otterberg who died in 1911 and there was a link to Find A Grave. At that link I found this obituary:
Note that brothers Andrew of North Dakota and Peter of Montana are mentioned at the end of the obituary.
As a result, our family learned that Andrew had a brother who had been forgotten, probably because he died earlier than his brothers and had no children.
Starting in 1905, South Dakota kept death records at the state level. Here is the death certificate I ordered from South Dakota for Ole (Olof) Otterberg:
More recently, I worked with a second cousin in Denmark and a friend of his in Sweden to locate Swedish Household Records in Skåne, Sweden for this family. Here is the Gluggstorp record from 1877 through 1866:
All three brothers are listed. In the Swedish record, Andrew is Andreas and Peter is Per. I also learned from this that the names of my second great-grandparents are Sven Svensson Otterberg and Gunilla Nilsdotter. Compare those names to the parents' names on the death records above. It just shows that you cannot always accept all the information on death records as accurate. It depends on who provided the informaton.
