Cross was born in
Nenagh in
County Tipperary, Ireland, on 29 September 1921. His mother died during her labour with him. His elder sibling had
intellectual disabilities and was consequently
institutionalised. Cross was raised on the family farm, which was a hundred acres (40 ha) in size, before moving in with relatives. He was nicknamed "Jasper" by his family and friends. Cross studied economics and political science at
Trinity College Dublin, where he graduated with a
first class honours degree in 1944. It was there that he also met his wife, Barbara Dagg, who studied modern languages. During
World War II, Cross served with the
British Army and fought for the liberation of France. He was commissioned into the
Royal Engineers Movement Control Section in 1944. After the war, Cross joined the diplomatic service and was assigned first to
New Delhi in 1953. His first stint in Canada commenced in 1957, when he served in
Halifax and
Winnipeg for five years. He was consequently assigned to
Kuala Lumpur for four years (in then
Malaya and after 1963
Malaysia), before going back to London in 1966 to direct the
Board of Trade branch in charge of exhibitions and fairs overseas. He returned to Canada in February 1968 as the senior Trade Commissioner in
Montreal. ==Kidnapping==
