Among the Papers of Nancy Jane Hinkle were notes on the births, deaths and marriages of the Applegate and the Ruppert Families. Nancy's mother was Mary Jane "Jennie" Shoemaker (1846-1923). In 1850 Mary Jane was listed with the Elizabeth and J. C. Applegate family as a four year old child named Mary J. Shumaker. Ten years later she was listed with the the same family as Mary J. Applegate. According to the Morrow-Thompson Tree on Ancestry.com, she was adopted at two years old. Her death certificate lists her biological father as Shoemaker, from England. Jennie Shoemaker married John Hinkle (1842-1909), son of Samuel Hinkle (1818-1870) in 1864 and moved from Gibson County up to Porter County in 1880, where John's sister Lavica Hinkle (1857-1922) and husband George Field (1849-1915) were living.
