Yes, there are many stories of alleged Spanish ancestors in the east-coast fishing villages. Some people think the Gosmans of my native East Neuk of Fife are descended from a wrecked Spanish sailor called Guzman. There is of course no proof of any of these stories, and surnames like Gosman, Stephen and Cordiner have been around in Scotland since long before the Spanish Armada.
On a more practical level, I know of a Mary Jean Cordiner from Boddam who married Peter Smith, known as "Poetry Peter", the fisherman-poet of Cellardyke (by Anstruther). I can't check the date of their marriage as Scotlandspeople is down, but Peter was born in 1874, and Mary Jean shows up in the 1901 census of Cellardyke, as a "visitor" with a family of Murrays, aged 22. The son of Peter Smith and Mary Jean Cordiner was a teacher at my old school in Anstruther in the 1960s and after retirement wrote several books about the local fishing industry.
