Does anyone know of an Augustus Koeppe who married Mattie May in DeKalb County, Indiana in 1888?

Am anxious to see if we are related! I do not have an Augustus Koeppe in our ancestry yet, but we never know.. Mine starts with Bernhardt & Dorathea Koeppe coming to USA in the late 1860's, as Grandpa Louis A. Koeppe was born in Wisconsin in 1870. Since I do not know if Bernhardt had any brothers or sisters, I am a total "dead-end". Please e-mail me directly...........June

My gr-grandfather was an August Koeppe born 1870 somewhere in Germany, immigrated? Had a brother Herman, and married a Mary Dicey Earl of Missouri. They settled in Pierce County Nebraska, but also lived at some time in South Dakota because my grandfather Walter was born there. Anyone related???

Walter G. Koeppe was not born in SD he was born in St. Bernard, NE
