The diary is full of the names of the people who lived in Ripley, Brown County, Ohio, in 1870. Oscar F. Shaw made an entry every day of the year except for December 31. The Shaw names are:

Oscar F.; America; George; Suzie; Ralph.
I followed the family by way of the censuses beginning with 1850. I believe that Oscar died very young because the younger children lived with their brother George in later censuses.
What are the Shaw names that you are looking for?
Whitten and Emery are not mentioned.
