A late response to Carrie Voss: My g-grandfather, William Henry Voss, had a brother named August Voss who was in Council Bluffs in 1909 when another brother, Fred, lost his son. William lived in State Center, IA and married Emma Wantz there in 1873; they moved to St. Joseph, MO in 1880.
William was born in Germany in 1848. William, August, and Fred Voss also had a brother named Henry who lived in Wisconsin.
Please contact me if your August Voss is possibly related to my g-grandfather William Voss. I have info on William's parents and John Voss's descendents and am trying to learn more about the August Voss in my family history.
