My mother does not know her mother's birth place in Iowa.Also, she does not know her great grandparents' names.However, I think that we are likely sharing information about the same people--Charles and Joe.
The family names are similar--Charles' sons names were:Charles, Harry, Joe, Ed, Lloyd, Fred, and Tom.
The girls' names were:Nel, Josephine, Jenny, and????
However, these are common English first names so it may not be significant.
I think that you should try writing to Marvin Rear at Leslieville-his father's writings would likely provide a lot of details.
