Is this the son of Joseph Cosmero who died in Yolo County in 1954? I believe his father, Joe, was married to my grandmother, Vivian Rogers Sternes. He was the only grandpa I ever knew, and didn't know he wasn't actually my real grandpa until I was much older. I thought he had a couple of sons who lived in the Merced area, but that's all I knew about his family. Grandpa Joe served in World War I and was gassed in France. He was born in the Canary Islands. I still miss him.
