U.S. States: Kansas: Mitchell County
Linda, I now know that Neil McKee, was the son of Milton McKee, who lived near Greenmound and Neil turns out to be my husband's 2nd cousin, once removed.
Milton's father, Seth, was the brother of my husband's great-grandfather, Sylvester McKee. I have to thank Vicki Mears who responded to my posting and gave me all sorts of information on that line.
I still don't know what the connection to the Pettersons is, but at least we know your memory hasn't failed you!
