Inspired by one of my second cousins, with whom (along with astrophysicist Stephen Hawking) I share MacGregor ancestors, I've dredged up the part of my file (mostly supplied by the late Rod Drummond of Auckland) that listd Rob Roy and some of his descendants. Note the John Drummond in generation 5, who married May MacGregor and ended up in the Tasman Region (part of Nelson Province) of New Zealand; descendants included Rhys Drummond, who married a daughter of my sister-in-law.
