I have information that says Jeremiah died in St Paul, Mn and is buried at Riverside Cemetery in St. Paul. My wife also descends from James Duncanson through William Duncanson's brother George. I am working on trying to update the John V Duncanson work "The Duncanson Family of Horton, Nova Scotia". You can find more at my website: http://www.duncanson.orghttp://www.duncanson.orgIf you have information that you would like to share, I would be more than happy to add it to the growing genealogy database that I am publishing on the web. Do you have more information on James? I have been looking for him for several years and have a couple prospects that I am researching. Please write back. I am trying to eventually create a clearing house on the descendants of James and eventually beyond him.
