I am trying to help someone whose maiden name was FREVERT. She is the daughter of Lenus who was the son of Fredrick and Hattie FREVERT. Fredrick was born in Indiana about 1876. His mother was Charlotte and I believe his father was Henry C. FREVERT. I did find a Henry C. and Charlotte listed in the 1880 census for Knox County, Vincennes Township in Indiana and they did, indeed, have a son, Frederick, and also a daughter Mary. In the 1900 census they are in Valley Township, Ellsworth County, Kansas and have 2 more children, Charlie and Willie. Any help would be greatly appreciated.
