William Colby Cooper was born 8 Nov 1867 in Missouri, and died 17 Jul 1962 in St. Helens, Columbia, Oregon. He was married to Mary Catherine Hazen 1 Aug 1897, in Warren, Oregon. His parents were Mack Cooper and Martha Sims. It is they for whom I am searching information. I would like their birth/marriage/death dates/places. If William had siblings, I would like to know that also. Mack may have been a nickname rather than his legal given name.
