Dates of birth and death of David Neff and Susan Wrightsman from Verle Ohmart's 5-generation chart. It does not list places for events, but according to his family group for their daughter Lydia and her husband Marion Ohmart, their wedding took place at David Neff's home near Girard, Macoupin Co., Illinois. So that is a good guess for where David and Susan died. Also, Lydia is said to have been born in Roanoke Co., VA, so David and Lydia may have married there.
