My Grandfather was William Walter Coen, he was born in Greene county IA, 1880. He had a brother Samuel Arthur Coen, I'm not sure if any of these names look familiar. William died in WA 1957. Samuel died in WY. I don't know if William and Samuel had other brothers and sisters. I believe William and Samuels fathers name was Richard, who married Minerva Nesler. I have not been able to get any further. I do have some background on Samuel's wife and children as well as Williams wife and children, But I have nothing else on this line of Coen. please e-mail me with response.
