You will be pleased to know that I can help you. More importantly, you have helped three or four Weipert researchers nail down an actual location in Germany other than Baden or Bavaria!
John Weipert, Sr., was born 7 Mar 1816 in Baden, Germany. He died 3 Mar 1897 near Lansing, Allamakee Co., IA. His wife was Franziska (last name unknown). She was born 22 Sept 1820 in Baden, Germany and died 9 Apr 1875 near Lansing. They are both buried at Gethsemane Catholic cemetery in Lansing.
The family arrived in America on May 17, 1854. I know of Katherina Weipert, I had her born Nov 1843 (census info). She had a sister, Mathe, born 1850 in Germany, and a brother, Ferdinand, b. 29 Jun 1848 in Germany. He died on 24 Aug 1908 in Lansing. He married a Helen Rippenberger.
In any case, you have found a connection. Email me at LDShoger@aol.com
and I should be able to get you some info one way or the other.
