Still a stone wall with this one which I haven't been able to progress. His wife died 11 December 1918 with the Spanish Flu at Cavan, Rathfriland, Co Down. Her father Henry Bell present at death. Last record I found of William Alexander is birth of his son David 26/09/1911. There is an inference that he may have perished in the Great War but I can find no suitable record of identification on CWGC.
