According to the Barre VRs, Mary died of "Lung Fever".
Middle name "Eugene" given by Douglas Harry Wheelock, great-grandson. The ancestry of Henry Eugene Wheelock is not known. A Henry Wheelock, age 16, is enumerated in the 1880 Census in Overfield, PA, living in the household of George Trauger; parents not given. This may be a different Henry since his implied birth date disagrees with that given in the Pennsylvania 1910 Miracode Index at Ancestry.com.
