I am looking for the name of the son of John E. Giebler of the Champion City Mill in Franklin County, Missouri. John's parents were Eberhard and Elizabeth Rapps Giebler. John married Bertha Weirich. John and Bertha's daughter was Della. The had a son who was also involved in the mill but I do not have his name. I am not related, but I just research local history. Thanks.
