This is the only track in Ultima V not composed by Kenneth W. Arnold to the best of my knowledge. Iolo and Gwenno were in-game characters based on David R. Watson and his late wife Kathleen Jones. I gather Jones was still living in 1988 and both contributed to the composition, but I cannot confirm that. Here is a wiki stub on Watson:

"David R. Watson is a bowyer currently living in Austin, Texas. He is the real-life inspiration behind the companion Iolo and composed the music for the song "Stones," which became a series staple following its initial appearance in Ultima V. Additionally, Watson is a fencing master and lutenist, with a varied career of video game support including level designer in X-COM: Apocalypse and lead mission analyst in Grand Theft Auto: San Andreas."
