Someone , probably more than 10 years ago, donated the transcript of a letter from Nelson Parker, written shortly before his death to his sister.I am the GGGrandaughter of his child who was adopted by our family (the Joyces). I am trying to trace Nelsons parents and on back . I am hoping to find the person who donated it so I can see if they have the envelope so I can verify the sisters name and get a location. And if thje donator is a desendant of Nelsons, to find some new relative.
