LONDONDERRY, NORTHERN IRELAND--Three sets of human remains dating to the seventeenth century have been uncovered within the walls of historic Londonderry. Archaeologists want to know who these people were and how they died. Could they have been victims of the siege of the Jacobite army in 1689? “The Siege of Derry certainly comes to mind but we don’t know if these remains are related as of yet,” said archaeologist Emily Murray. “Sieges are usually associated with mass burials,” added Eamon Ó Chiardha of the University of Ulster.
