This is what I found in the library. No obit in the toledo Blade for Rachel, or anyone dieing in 1940. There is a obit for Rosco Mcknight who died in Sarasota, Fl. Obit in Blade on 11 Nov. 1963. It states surviving wife Edna L.; sons, Rosco Jr. and Daniel both of Whitehouse, Oh.;Thomas, Charles,Timothy, Robert, John, all of Bradenton, Fl. some daughters, but scribbled out on micro film of whole page. brother John Frederick of Muncie, IN. and 13 grandchildren. Funeral handled by Pierstorff Mortuary, burial in Ottawa Hills Memorial Park. There are several other McKnight's obits on file if you have any other names to look up. I'll look up the funneral home to see if it is still here.
