That's a very detailed accounting, Jesse. It would be nice to see an update, as this post is almost 12 years old now. I know that BAT still owns the Dunhill TM as it applies to tobacco products, and Richemont/Remgro still control BAT, and the Rupert family still controls the whole lot, but I'm not certain of all the details.Here's a recounting of the various permutations of Dunhilldom. You'll see who owns what.
