Forum:Grandmaster of the Six Samurai

I'm using a Six Samurai deck, however when I was playing against a few of my friends, I had some cards that affect "Six Samurai" Monsters. We aren't sure, but does the Grandmaster of the Six Samurai count as a Six Samurai monster? The words Six Samurai are in his name. Also, would those card affects also affect "Six Samurai Chamberlain"(I think that's the card's name) and "Hand of the Six Samurai"? Thanks for the help.
