I am looking for any information that has to do with the family of Ludwig(Louis) Oldenburg. Louis was born in Germany May 1847. He married Caroline Wendorf 1861-68 in Germany. Caroline was born in Germany May 1838. The family came to the U.S. in 1873/74 and settled in Brown County (Howard, then Green Bay) Wisconsin. They had four daughters who show up in the census' with them. Louisa b. January 1876 in WI Augusta b. Abt. 1864 in Germany Alvina b. April 1880 in WI Bertha b. February 1873 in Germany. Louisa married Solomon Cartier and Bertha married William Frederick Kersten. Caroline states in both the 1900 and 1910 census' that she has had 8 children and they are all still alive. I have no idea who the other four children are. Any information would be greatly appreciated.
