The Frederick K. Neumann Home Page

I am researching my Grandfathers family. His name was Frederick K. Neumann he married Lois Pauline Margruerite Deeter on April 7, 1917. His father was Julius Vernon Neumann married to Roslie Myrtle Galdwin. His father was Frederik Neumann married to Mary Jane Grant. I have been told she was the sister to President Grant. However, I've not found any information that it is true. If anyone has more information I would appreciate you contacting me.
