escaped amid the confusion when the ship sunk. He believes that a prisoner by the name of Brookes also managed to escape at the same time. The reason for this theory is that on the 2 November in 1851, A William Rosser married Maryna Hendrina Maria Cordier in Ladismith, and on the same day in the same church a William Brooks married her mother the widower Anna Petronella (nee Hartman)
