Mary Lynn (Rattermann) Knochelman
Mary Lynn is a cousin of Margaret's. Her home is in Cincinnati.
The chart of her immediate family is here.
She has graciously become my 'right hand' in that city. She has done a wonderful job of tracking down and photographing grave markers, and also the 'Ratterman' street sign. Here are photos of her in action.
It took some doing, but she found the elusive burial site of the famous
 'H A' in the Spring Grove Cemetery.
