I have since learned I was in error in claiming Snedeker as the surname for my Mary Ellen; thus Wm W. was not married to my Mary Ellen. I have learned her surname was WINICK or some like spelling. So, I am still searching for the given name for my McKEE and for the family of my Mary Ellen.
Also, Mary Ellen WINICK & (--) McKee may have married in a neighboring state. Their son Ralph Clarence was born somewhere in IL in 1860. Oh my! Juanima
