Not sure if you're still researching your family tree, but I'm a storyteller in Aberdeen researching interesting stories around New Deer and found this...
I was surprised to find the details to be correct (the names and locations are usually a bit vague) and that Tam Craig did indeed reside at Nether Hythie in the early 1800s (newspaper cuttings confirm this) Thought you might be interested :)
(Myths and Superstitions of the Buchan District)
Tam Craig, who resided at Nether Hythie, Old Deer in the beginning of the nineteenth century, was a master mason of some repute in his day. He was not only a shrewd businessman, but he was also reputed to be deeply versed in all the mysteries of the Masonic craft. Having at one time found some of his tools missing, and suspecting that they were stolen, he made inquiries amongst his workmen about them, but all denied having any knowledge of their whereabouts. At last one night he summoned his workmen to meet him in a loft at his farm steading, and when they were all assembled, he plainly told them that he suspected someone in the squad had stolen his tools. Of course all denied the theft, or knowledge of where the tools were. HE then told them that they knew that his craft gave him power to summon an agent who would soon point out the thief. So, after performing or going through some incantations which were clearly recognised as a summons to “Auld Hornie” to come forward and point out the thief, a firlot measure that was lying in the apartment bottom uppermost began to move, and a sulphurous smell pervaded the apartment, and then the firlot moved slightly up, and a blue sulphurous light shone out below the edges. Instantly one of the men roared out in terror – “Oh haud him back and I’ll gie ye back yer teels!” Tam gave the sign and the firlot measure fell down and smothered the pale blue flame. The man confessed that he had stolen the tools, and told where they were hidden. In after years the secret was known. Tam had an accomplice below who introduced a burning brimstone candle into the firlot through a hole in the loft.
