In the 18th century Elizabeth St. Clair song MS (also called the Mansfield MS) there are two versions of a song relating to Bamborough Castle, but there is nothing relating to Rosline Castle. One text of one of the songs is "The Laidley Worm of Spindleston Heughs" which Child gave as an appendix to "Kemp Owyne", #34. There is nothing about Templars in the song however.
