Ona Willson was probably born about 1860. I found her math book in a pile garbage from a house that was being gutted and would like to get it to her family. It is in pretty rough shape, but has many sentiments inscribed by her. She signed her name and noted that the book was purchased May 26, 1878 at Sugar Valley, OH, but also has written Eaton, Preble County, OH several times. She also lists her classmates names, and some have signed her book.
