The more I learn about the McGrouther/McGruther/McGruder family in Scotland the more outlandish it seems to imagine they were part of Clan Gregor or that Alexander ever identified himself as a MacGregor. The Drummond family, to whom the McGruders were connected for many generations, were closely allied with the Glenorchy Campbells, with whom the MacGregors feuded bitterly. And, more particularly, the Drummonds and McGruthers had a powerful reason to feud with Clan Gregor themselves. See the new page I’ve just put up, with the same title as this post, under the heading Scotland.
