This was in the Quinion citation. It's obsolete for fur trader. Did fur used to be fell?

Also, I did not know the meaning of fey, as given in the Straight Dope site. I'd always thought it did mean otherworldly, but not particularly associated with death.

And, speaking of sayings, I wrote to someone that I had cooked "up a storm" the other day. My mother always used that expression. Is this common in other places, to mean "a lot"? Hmm, come to think of it, it usually means to do a lot in one fell swoop!
