I just saw Frankenweenie last night. There was a scene where casks of beer spilled on the ground. In a few clear shots, the side of the casks said "Drie Molens", which I took to be a combination of Drie Fonteinen and De Molen. Subtle, fun craft beer reference from Tim Burton.
Well if you translate you translate Drie Fonteinen into English you get "Three Fountains". Translate de Molen into English and you get "The Mill". Doesn't really matter which language you choose to combine them in, same meaning. Given that it was on a cask of beer, I choose to believe.
I mean, you could be right, but my point is that "Three Mills" seems like a perfectly inconspicuous phrase to put on a barrel, unlike, say, "Kanty Lune."
