August Emil Rosentreter is buried in Kingsbury, LaPorte Co, Indiana with his first wife Hattie Francis Shigley. August's second wife Susan Jane Alexander is buried in St Joseph Co, Indiana. If I am right, your Richard B. Rosentreter is my grandfather's brother. Herman Edward Rosentreter is my grandfather. He lived in LaPorte most of his life.
I have seen August's name spelled with an extra "a" at the end of his name. His headstone does not have the second "a"
I hope you are still around! It has been awhile since your post.
