Alex, there are lots of points for discussion in your paper. On one point, the MacMaurices who were supposedly descended from Buchanans, we see what appears contradictory evidence in the DNA results for McMorrises in Group F of the Morrison DNA Project. These McMorrises settled in County Tyrone in the North of Ireland. They match the Y-DNA of a number of Morrisons, but no Buchanans. These are apparently the only McMorrises for whom DNA results are available. The Buchanan DNA Project has stated there are no McMorrises who match Buchanans in that project. Settlement records for County Tyrone indicate the McMorrises there settled at the same time as other families from the Loch Lomond area, including Buchanans, Colquhouns, MacFarlanes, etc.
