I am a McGillis. My Gr. Grandfather was Duncan Neil McGillis he married Victorie Sarah Jeneau. They settled in Harrisville,MI area Alcona County. In the town of Harrisville, MI there is a church called St. Anne and their cemetery across the street. McGillis's are buried there too. Duncan and wife Sarah Jeneau. Laughlin is there also. I went to the cemetery in Mikado and I saw a William McGillis buried there. I'm not sure if he is in my tree. Maybe that will help you.
