I have a very nice photo I picked up at an antique shop of William Cooper and I am trying to get it back to a descendant. In researching him I find he was born Mar 29, 1881 in Yale, St. Clair Co, Michigan to James Cooper and Emeline Chaney/Cheney. He married first to Jennie McGregor in 1903 and she died 1905. He married second to Catherine "Kate" Helwig from Cass City, Tuscola Co, but from the census it appears they had no children. William died in Flint, Genesee Co, Michigan on Nov 30, 1940 and Catherine died Mar 17, 1947 in Cass City, Tuscola County.
The back of the photo says "William Cooper, dec., son of James Cooper of Yale, Mich and Kent County. James Cooper is Pa's uncle. Grandpa's youngest brother,"
Let me know if this is your ancestor and I will mail the photo to you.
