I think your grandfather was my uncle. Was he born in Michigan in 1877? I have a cousin named Pauline daughter of Maude Shier Valet Jensen, she used to live in Amity, Oregon. I also had uncle named Walter Shier that lived in Grants Pass. Passed away in 1962 there. I remember my mother, Minnie L Johnston, talking about some Colton's she said were my cousins. I am doing the family history now, so feel free to contact me via e-mail.
