This is not a letter so much as a list of people and dates hand written on the back of Stanley's original inquiry addressed to Pearl Hungerford. She begins the list with George Hungerford, father of Jean Du Bois Hungerford (she provides no information about George Hungerford). The list is not dated but the envelope in which it was mailed shows an 11 June 1975 postmark.
