Elizabeth Koch Bischoff was my great-great-grandmother. She was the first wife of Henry Bischoff and was born about 1859 in Germany. She died in 1888 in Amherst, Lorain County, Ohio. Henry and Elizabeth were married in 1881 in Lorain County and their children were Mary, Anna, Martin, and Elizabeth. I find Henry Bischoff and his second wife in 1900 and 1910 census records living next to a Henry Koch, who I think was probably Elizabeth's brother. According to familysearch online records, this Henry Koch was born 21 Aug 1855 in Germany to Henry Koch and unknown mother. He died 20 Mar 1923 in Elyria, Lorain Co. I would love to compare notes with anyone connected to this family!
