There does appear to be a Scottish clan, but the name can also be from West Norway. The island of Holsenøy, to the northwest of Bergen, has a small farming area with a small lake with the name "Ryland." Some who live there, or lived there in the past, took their name from this area. How the area got the name is still uncertain.
As for the Scottish origins, I can't be of much help. Sorry.
