I've found further information regarding Elizabeth Blair Robertson...she was married to John Armit and after marriage in Lochgelly in 1914 John & Elizabeth settled in Newmains, Lanarkshire. Unfortunately, John Armit succumbed to the Spanish Flu in 1918 so Elizabeth returned to her folk in Lochgelly but she never remarried. I suppose it's possible that she was buried in Cambusnethan cemetery with John.
However, I have discovered that John & Eliz had a daug, Isabella McCrum Armit in 1914 and that she married Robt Scott. She died in Lochgelly aged 53 in 1967. Is it possible you have a headstone for her?
When Eliz Armit (nee Robertson) died in 1949 the informant was Henry Robertson, son of Lochgelly but I have no information about him.
