Uncle Edward and Aunt Miriam???

Does anyone know who Uncle Edward and Aunt Miriam are?  The only Edward I can find is the eldest brother of Jane Roberts Riley (Thomas Roberts Riley's mother).  Theda Hill sent me the great picture and written on the back says "Uncle Edward and Aunt Miriam and their family".  I have tried researching Edward Roberts but I cannot find one who married a Miriam.  Any ideas???
