We have corresponded in the past, but I think at the time you were focussing more on Ireland. My family also descends from the Morrison, or Mylvorrey family from Glenshuggal, Ballaugh, as will many a thousand others. Glenshuggal is in Ballaugh Glen. Very attractive area. The Morrison line who still live in the glen, (eldest son inheriting the land from each generation), has femaled out, and carries the name Wade, another old family from the area.
Although I have met the family and of course, not living awfully far away, I know Ballaugh Glen, I have not had the a good look around the private areas, although I have been invited.
Tim, a contributor to this page, I believe has visited and met the family in connection with his branch.
