A group of Scottish people who are related to Rob Roy, a guy who got beaten up by Liam Neeson, even though Liam Neeson is actually Irish.
My uncle is a MacGregor, and he still hates Liam Neeson for that movie.
I saw a MacGregor in the park and he looked like he was about to cry.
My teacher said Rob Roy was a MacGregor, and now I hate history.
