Hello again, the three names have been checked and are on the headstone and I think I have partially solved the mystery. Robert Norman married Mary Margaret Leahy in Cork in 1920. Mary had a sister Catherine Frances. She married Wilfred Mather (a soldier stationed at barracks in Cork) in 1921 in Cork. They had a daughter, Amy M Mather, whom I assume married Mr Malone but I cannot find the marriage. The only puzzle is why you would want to be buried in a plot with your brother in law's mother, so no blood relation, when your sister had already moved to London! I cannot find Wilfred or Catherine/Frances Mather on the Scottish electoral rolls, but there is an Amy M Malone living in Edinburgh at the right time. As they are not blood relatives I will not pursue this line any further. Thanks for your help and interest. Regards
