This information is completely amazing!! Stephen and Mahala are my great grandparents. To answer some of the questions, Stephen is buried in the Whitewater cemetery between his two wives - Josephine and Mahala. He had no headstone so my mother made a cross for him. I understand that Josephine died during childbirth and so did the child. I did not know they were from Canada but did know that his father Edward came from England. It is correct that Mahala died in St. Charles township at the home of her daughter Nina McDougall. Nina and Verne married brother and sister Clarence and Francis McDougall. They had a sister Nina also so it gets a little confusing.
The mother to Mahala is Susana Turner who was born in Pennsylvania but spent most of her life in Beaver. Susana was American Indian - I am not sure how but photos of her certainly prove that plus some of the relatives were able to collect money from the casinos because of this.
Mahala and Stephen lived in Fairwater before their death. The parcel of land is still in the name of Stephen Graves. Verne moved onto the land and raised his children there.
You talk about Peter Harmon who was born in 1883. He did not live in Fairwater but lived 3 miles to the north in Elba. When Peter's wife died and he wanted to move to St. Charles, he sold his small farm to my dad Russell Graves. I'm not sure of the date of his death but would say it was in the 1960's.
Edward and Minnie that were buried in the Whitewater cemetery both died - I believe in 1913 from what was then a bad flu which later we knew it as the "Swine flu". In the last few years someone moved the bodies to Hillside Cemetery in St. Charles. Only the headstone remains in Whitewater. I do not believe this is the father to Stephen but could be a brother. Edward is the name of Stephen's father however.
