I was just browsing the newspaper today and read that Peter Ebert and his wife Sophia Bast Ebert celebrated their golden wedding anniversary at the home of their son-in-law Christ. Rasch, in South Chicago. They had been living in Milwaukee since 1862, but then moved to Kansas City to live with their son about 5 years previous to this event. Both were born in Treptow (on the Rega River) Pommern, but were married in Zinndorfe, Pommern.
Later on, there are death notices but no obituaries published for the couple! Maybe you got all this from the library already.
"Milwaukee's German Newspapers; an index of death notices and related items" (1844-1950).
