I am searching for a death date, obituary, or cemetery record of Herman and Fredricka Hanneman who lived in Barnum, Minnesota around 1900 to 1910. I have census records that indicate they lived there in 1900 and 1910. I believe they had two or three daughters. Fredricka was a sister to my Great grandfather August Rupnow. I believe there were two other brothers in Germany. She immigrated to the US in 1893.
