The Clan Morrison Society of North America has a DNA project. They place participants in groups based on DNA results and geographic location of most distant known ancestor.

Here is a link to the groups shown on a map. (Click on Morrison DNA Project on the left side under news)

Here is a link to the results of those tested so far. You can look through the most distance ancestors and see if there is someone you know from your own research.
