Christie, B. 1995. The Horses of Sable Island. 2nd Edition. Pottersfield Press.

 Extract, page 70:  "They are said to have been taken to their sandy home by the Norsemen, or Cabot, by Baron de Lery in 1518, by Portuguese fishermen in 1582, by the Marquis de La Roche-Mesgouez in 1598, and by Acadian horse ranchers in the early 1700s. They are said to have descended from those escaping from an undated, unnamed Spanish wreck, from those surviving the wreck of a vessel out of Le Harve, France, that was on its way to Quebec, again, undated and unnamed. They are said to have their roots in horses being transhipped from Massachusetts in yet another unnamed vessel, said to have been wrecked on Sable Island around 1800. The history of the island and the possibility of some of these fables being true has already been given. The readers must judge for themselves the probablilities for the remainder."
