According to another tree on Ancestry.com - she actually died in Florida on June 2, 1992. I know that she passed away in the 1990s and I will try to get out to the library to get a copy of the obituary for you - probably would be faster then finding the one I have.
The tree info has her birth name was Marjorie Blanche Micklatcher born April 5, 1922....not sure if the 5th is correct - as I always heard her birthday was April 8th.
