There are clips from a program that the Smithsonian Channel has done that you can watch from their online video player for more about Duffy's Cut and the story of the Irish men.
Below is the link to the video player. Once there you will have to select History and Mystery, and then scroll way downto 3 separate clips: The Ghost Hunt Begins, the Mystery of Duffy's Cut,and The Costliest Mile. http://link.brightcove.com/services/player/bcpid1155838635
But if that doesn't work, try going into the http://www.smithsonianchannel.com/site/smithsonian/home.do and then from there, go to video, and so forth.
Being half Irish, I will be very interested in the outcome of the DNA results on the remains. Natalie SiemborHistorical Research ServicesOswego, NY
